I asked some experts about that. The responses was the UI and because there isn't as big a user list.

what is UI?

User interface

meaning the way it is set up and how you view the plurks.

thanks Tech_Teacher13

lmiller: No problem

Arent't those are the same people who gritch all the time about how people aren't flexible enough to embrace the new?

A larger community of users there, I think.

The UI!? Uh, Tweetdeck is the closest thing to a usable T UI, & it still stinks. Give me a break.

I think it's related to the huge number of followers some of the "big names" have in twitter also

100% agree. It is the "superstar" effect. But they are not exactly "social." Plurk allows ANYONE to interact, but Tweetdeck filters out ALL

but the folks you choose in your main clique column. And they run a very small, tight clique.

I heard one say his 4200 followers were his personal tech support. When he asks a questions, someone always answers. I have to wonder though

what happens though if he only follows 50 or so.... he never sees the questions of the other 4150 folks so how can he reciprocate?

so, it might not be the best at facilitating conversation, but here's another interesting aspect of twitter.
