It might not be so hard:

As I see it, the biggest shortcoming of social-networking sites is their inability to play well with others. Between MySpace, Facebook, LinkedIn, Tribe, Pownce, and the numerous also-rans, it seems as if maintaining an active presence at all of these sites could erode into becoming a full-time job. If Google can somehow create a means for all of these services to work together, and seamlessly interact with the Google family, then perhaps this is the killer app that people don’t even realize they’ve been waiting for.

Some might take issue at Wolf’s presumption. Many of us have realised in 1997 that the “killer app” for social networking services is for them to work together. But the point is incredibly important and needs to be made again and again.

Social Networking Services work when people connect through it. The most intricate “network effect” you can think of. For connections to work, existing social relationships and potential social relationships need to be represented in the SNS as easily as possible. What’s more, investing effort and time in building one’s network relates quite directly with the prospective life of SNS. Faced with the eventuality of losing all connections in a snap because everybody has gone to “the next thing,” the typical SNS user is wary. Given the impression that SNS links can survive the jump to “the next one” (say, via a simple “import” function), the typical SNS user is likely to use the SNS to its fullest potential. This is probably one of several reasons for the success of Facebook. And Google can certainly put something together which benefits from this principle.

Yeah, yeah, Wolf  was referring more specifically to the “synchronisation” of activities on different SNS or SNS-like systems. That’s an important aspect of the overall “SNS interoperability” issue. Especially if SNS are important parts of people’s lives. But I prefer to think about the whole picture.

Another thing which has been mentioned is the connection Google could make between SNS and its other tools. One approach would be to build more “social networking features” (beyond sharing) into its existing services. The other could be to integrate Google tools into SNS (say, top-notch Facebook applications). Taken together, these two approaches would greatly benefit both Google and the field of social networking in general.

All in all, what I could easily see would be a way for me to bring all my SNS “content” to a Google SNS, including existing links. From a Google SNS, I would be able to use different “social-enabled” tools from Google like the new Gmail, an improved version of Google Documents, and the Blogger blogging platform. Eventually, most of my online activities would be facilitated by Google but I would still be able to use non-Google tools as I wish.

There’s a few tools I’m already thinking about, which could make sense in this “Google-enabled social platform.” For one, the “ultimate social bookmarking tool” for which I’ve been building feature wishlists. Then, there’s the obvious need for diverse applications which can use a centralised online storage system. Or the browser integration possible with something like, I don’t know, the Google toolbar… 😉

Given my interest in educational technology, I can’t help but think about online systems for course management (like Moodle and Sakai). Probably too specific, but Google could do a wonderful job at it.

Many people are certainly thinking about advertisement, revenue-sharing, p2p for media files, and other Google-friendly concepts. These aren’t that important for me.

I can’t say that I have a very clear image of what Google’s involvement in the “social networking sphere” will look like. But I can easily start listing Google products and features which are desperately calling for integration in a social context: Scholar, Web History, Docs, Reader, Browser Sync, Gcal, Gmail, Notebook, News, Mobile, YouTube, Ride Finder, Blog Comments, Music Trends, University Search, MeasureMap, Groups, Alerts, Bookmarks…

Sometimes, I really wonder why a company like Google can’t “get its act together” in making everything it does fit in a simple platform. They have the experts, the money, the users. They just need to make it happen.

Ah, well…
