Are you aware of any open web work / uses / examples on/of the social graph? If so let me know!
The social graph is often a useful discovery tool for instance, and can be a navigation aid online. If you’ve ever looked at the blogroll of a blogger you follow, to find other bloggers to follow in your feed reader, you know what it’s like.
I’m interested in localised, fragmentary, starting from you/me, types of social graphs, out on the open web. I’m aware of some academic work in the early ’00s exploring and visualising the social graph of cross-blog conversations, and of course there used to be FOAF but mostly without interesting examples of usage attempts.
One thing that might be interesting is making RSS feed lists and blog rolls traversable. E.g. I have a blogroll that includes Peter who also publishes his blogroll. Both those blogrolls are in OPML, and OPML allows inclusion of external material formatted in OPML. I can include Peter’s OPML list in my OPML list. Then from my blogroll you are able to browse Peter’s blogroll. Or use a reader that actually includes it directly from its source. If Peter included my blogroll that way, and others that people publish than one could traverse across multiple includes. Etc.
