As a follow-up on my previous post…

(I was looking for the origin of the “10 years or 10,000 hours to be an expert” claim.)

Interestingly enough, that post is getting a bit of blog attention.

I’m so grateful about this attention that it made me tweet the following:

Trackbacks, pings, and blog comments are blogger gifts.

I also posted a question about this on Mahalo Answers (after the first comment, by Alejna, appeared on my blog, but before other comments and trackbacks appeared). I selected glaspell’s answer as the best answer
(glaspell also commented on my blog entry).

At this point, my impression is that what is taken as a “rule” on expertise is a simplification of results from a larger body of research with an emphasis on work by K. Anders Ericsson but with little attention paid to primary sources.
The whole process is quite satisfying, to me. Not just because we might all gain a better understanding of how this “claim” became so generalized, but because the process as a whole shows both powers and limitations of the Internet. I tend to claim (publicly) that the ‘Net favours critical thinking (because we eventually all claims with grains of salt). But it also seems that, even with well-known research done in English, it can be rather difficult to follow all the connections across the literature. If you think about more obscure work in non-dominant languages, it’s easy to realize that Google’s dream of organizing the world’s information isn’t yet true.

By the by, I do realize that my quest was based on a somewhat arbitrary assumption: that this “rule of thumb” is now understood as a solid rule. But what I’ve noticed in popular media since 2006 leads me to believe that the claim is indeed taken as a hard and fast rule.

I’m not blaming anyone, in this case. I don’t think that anyone’s involvement in the “chain of transmission” was voluntarily misleading and I don’t even think that it was that essential. As with many other ideas, what “sticks” is what seems to make sense in context. Actually, this strong tendency for “convenient” ideas to be more widely believed relates to a set of tricky issues with which academics have to deal, on a daily basis. Sagan’s well-known “baloney detector” is useful, here. But it’s also in not so wide use.

One thing which should also be clear: I’m not saying that Ericsson and other researchers have done anything shoddy or inappropriate. Their work is being used outside of its original context, which is often an issue.

Mass media coverage of academic research was the basis of series of entries on the original Language Log, including one of my favourite blogposts, Mark Liberman’s Language Log: Raising standards — by lowering them. The main point, I think, is that secluded academics in the Ivory Tower do little to alleviate this problem.

But I digress.
And I should probably reply to the other comments on the entry itself.

Nice!

At 20:27 (EST) on Saturday, November 17, 2007, I post a blog entry on the archaic/rare French term «queruleuse» (one equivalent of “querulous”). At 20:54 (EST) of the same day, Google is already linking my main blog page as the first page containing the term “queruleuse” and as the fourth page containing the term “querulente.” At that point in time, the only other result for “queruleuse” was to a Google Book. Interestingly enough, a search in Google Book directly lists other Google Books containing that term, including different versions of the same passage. These other books do not currently show up on the main Google search for that term. And blogs containing links to this blog are now (over two hours after my «queruleuse» post) showing above the Google Book in search results.

Now, there’s nothing very extraordinary, here. The term «queruleuse» is probably not the proper version of the term. In fact, «querulente» seems a bit more common. Also, “querulous” and “querulent” both exist in English, and their definitions seem fairly similar to the concept to which «queruleuse» was supposed to refer. So, no magic, here.

But I do find it very interesting that it takes Google less than a half hour for Google to update its database to show my main page as the first result for a term which exists in its own Google Books database.

I guess the reason I find it so interesting is that I have thought a bit about SEO, Search Engine Optimization. I usually don’t care about such issues but a couple of things made me think about Google’s PageRank specifically.

One was that someone recently left a comment on this very blog (my main blog, among several), asking how long it took me to get a PageRank of 5. I don’t know the answer but it seems to me that my PageRank hasn’t varied since pretty much the beginning. I don’t use the Google Toolbar in my main browser so I don’t really know. But when I did look at the PR indicator on this blog, it seemed to be pretty much always at the midway point and I assumed it was just normal. What’s funny is that, after attending a couple Yulblog meetings more than a year ago, someone mentioned my PageRank, trying to interpret why it was so high. I checked that Yulblogger’s blog recently and it has a PR of 6, IIRC. Maybe even 7. (Pretty much an A-List blogger, IMHO.)

The other thing which made me think about PageRank is a discussion about it on a recent episode of the This Week in Tech (TWiT) “netcast” (or “podcast,” as everybody else would call it). On that episode, Chaos Manor author Jerry Pournelle mused about PageRank and its inability to provide a true measure of just about anything. Though most people would agree that PageRank is a less than ideal measure for popularity, influence, or even relevance, Pournelle’s point was made more strongly than “consensus opinion among bloggers.” I tend to agree with Pournelle. 😉

Of course, some people probably think that I’m a sore loser and that the reason I make claims about the irrelevance of PageRank is that I’d like to get higher in a blogosphere’s hierarchy. But, honestly, I had no idea that PR5 might be a decent rank until this commenter asked me about. Even when the aforementioned Yulblogger talked about it, I didn’t understand that it was supposed to be a rather significant number. I just thought this blogger was teasing (despite not being a teaser).

Answering the commenter’s question as to when my PR reached 5, I talked about the rarity of my name. Basically, I can always rely on my name being available on almost any service. Things might change if a distant cousin gets really famous really soon, of course… In fact, I’m wondering if talking about this on my blog might push someone to use my name for some service just to tease/annoy me. I guess there could even be more serious consequences. But, in the meantime, I’m having fun with my name’s rarity. And I’m assuming this rarity is a factor in my PageRank.

Problem is, this isn’t my only blog with my name in the domain. One of the others is on Google’s very own Blogger platform. So I’m guessing other factors contribute to this (my main) blog’s PageRank.

One factor is likely to be my absurdly long list of categories. Reason for this long list is that I was originally using them as tags, linked to Technorati tags. Actually, I recently shortened this list significantly by transforming many categories into tags. It’s funny that the PageRank-interested commenter replied to this very same post about categories and tags since I was then positing that the modification to my categories list would decrease the number of visits to this blog. Though it’s hard for me to assess an actual causal link, I do get significantly less visits since that time. And I probably do get a few more comments than before (which is exactly what I wanted). AFAICT, WordPress.com tags still work as Technorati tags so I have no idea how the change could have had an impact. Come to think of it, the impact probably is spurious.

A related factor is my absurdly long blogroll. I don’t “do it on purpose,” I just add pretty much any blog I come across. In fact, I’ve been adding most blogs authored by MyBlogLog visitors to this blog (those you see on the right, here). Kind of as a courtesy to them for having visited my blog. And I do the same thing with blogs managed by people who comment on this blog. I even do it with blogs by pretty much any Yulblogger I’ve come across, somehow. All of this is meant as a way to collect links to a wide diversity of blogs, using arbitrary selection criteria. Just because I can.

Actually, early on (before I grokked the concept of what a blogroll was really supposed to be), I started using the “Link This” bookmarklet to collect links whether they were to actual blogs or simply main pages. I wasn’t really using any Social Networking Service (SNS) at that point in time (though I had used some SNS several years prior) and I was thinking of these lists of people pretty much the same way many now conceive of SNS. Nowadays, I use Facebook as my main SNS (though I have accounts on other SNS, including MySpace). So this use of links/blogrolls has been superseded by actual SNS.

What has not been superseded and may in fact be another factor for my PageRank is the fact that I tend to keep links of much of the stuff I read. After looking at a wide variety of “social bookmarking systems,” I recently settled on Spurl (my Spurl RSS). And it’s not really that Spurl is my “favourite social bookmarking system evah.” But Spurl is the one system which fits the most in (or least disrupts) my workflow right now. In fact, I keep thinking about “social bookmarking systems” and I have lots of ideas about the ideal one. I know I’ll be posting some of these ideas someday, but many of these ideas are a bit hard to describe in writing.

At any rate, my tendency to keep links on just about anything I read might contribute to my PageRank as Google’s PageRank does measure the number of outgoing links. On the other hand, the fact that I put my Spurl feed on my main page probably doesn’t have much of an impact on my PageRank since I started doing this a while after I started this blog and I’m pretty sure my PageRank remained the same. (I’m pretty sure Google search only looks at the actual blog entries, not the complete blog site. But you never know…)

Now, another tendency I have may also be a factor. I tend to link to my own blog entries. Yeah, I know, many bloggers see this as self-serving and lame. But I do it as a matter of convenience and “thought management.” It helps me situate some of my “streams of thought” and I like the idea of backtracking my blog entries. Actually, it’s all part of a series of habits after I started blogging, 2.5 years ago. And since I basically blog for fun, I don’t really care if people think my habits are lame.

Sheesh! All this for a silly integer about which I tend not to think. But I do enjoy thinking about what brings people to specific blogs. I don’t see blog statistics on any of my other blogs and I get few enough comments or trackbacks to not get much data on other factors. So it’s not like I can use my blogs as a basis for a quantitative study of “blog influence” or “search engine relevance.”

One dimension which would interesting to explore, in relation to PageRank, is the network of citations in academic texts. We all know that Brin and Page got their PageRank idea from the academic world and the academic world is currently looking at PageRank-like measures of “citation impact” (“CitationRank” would be a cool name). I tend to care very little about the quantitative evaluation of even “citation impact” in academia, but I really am intrigued by the network analysis of citations between academic references. One fun thing there is that there seems to be a high clustering coefficient among academic papers in some research fields. In some cases, the coefficient itself could reveal something interesting but the very concept of “academic small worlds” may be important to consider. Especially since these “worlds” might integrate as apparently-coherent (and consistent) worldviews.

Groupthink, anyone? 😉
