As Google Chrome for Mac (dev-channel) goes available with Extensions, I’ve started to use it as my primary browser. More extensible than Safari, faster than Firefox, Google Chrome is really good browser. Simple, but efficient.
Chrome is even easy to develop extensions on top of its extensibility. So this is my first Chrome extension called Social Graph Analyzer.
How to Use
By installing Social Graph Analyzer shows person icon on top right of your browser. To use this extension, just click this button on profile page of someone on any social services. By clicking it, pop up show up his / her other services’ profile page link. Of course, you can click them to see those pages.

I won’t describe how this is implemented, but if those profile pages include technologies like microformat or FOAF, detection possibility will go up.
In the future
Planning to show badge, how many sites are detected before clicking the button. Tracing social graph sounds nice too.
Twitter is a good place to try out. Check it out.
