I would love to see the stats on the numbers of direct, @, and general twits mapped against the total followed and followers per Twitter user.
I think the tighter connections are in the direct messages, then the @ messages. I think these messages reveal who are the closer ties in followed and follower lists.
Would be interesting to know percentage of private twitterers, also (and mobile and such, too).
Yeah, wondering a lot about how social networks map across Twitter.
Next time I per chance bump into Ev, I’ll ask. But, there are some of you who know him or will see him sooner than I. Indeed, I think he’s at Le Web, so maybe you could ask him there and let me know!
