Updated 2006-03-13 21:40 MDT: *sigh* Whatever Twitter is, one thing it isn’t at the moment is fast. I’m taking out the JavaScript badge so that the page will actually load.

Updated 2006-03-09 8:56 MST: I have edited this post a billion times over the past half hour trying to get the JavaScript badge to work; turns out that WordPress is very fussy about JS within posts.

Iris asks for someone to throw her a clue on Twitter, the microblogging, what-I’m-doing-this-second, IM/SMS/Web dealybop that is the flavor of the moment.

I mentioned it in my post on Monday and I have been messing around with it since.

The setup is that you enter a brief message (140 characters or less) that answers the question “What are you doing?” You can subscribe to friends’ messages and keep up with what they are doing. You can see it all on the web, or you can get IM or SMS updates (though I can’t get the IM updates to work for me on Adium for the Mac). Required background reading from Liz Lawley and Anil Dash.

It’s like a new online toy. I think that the hour-by-hour update is a big waste of time (note to self: stop doing that), but I could see using it once or twice a day as a little update on what’s going on with me.

I don’t know if I’ll continue to use it much, and I doubt I’ll continue to keep a Twitter window open all day, but I could see using it as Evan Williams does as a brief status line across the top of the blog.

David Rothman wants to know why should libraryfolk care about Twitter?. It has–as far as I can tell–nothing to do with libraries, but it does have something to do with groups of people who know each other to some degree, but don’t see each other much, who want to keep in touch in a relatively non-obtrusive way. People like library bloggers–my imaginary friends.

Twitter is also making a big push at South by Southwest Interactive this year. They encourage people at that conference to add sxsw as a friend, and then they can track everyone at the conference. I can see this at a conference like Internet Librarian, where attendees could just Twitter where they are going for dinner or their present location if they want company, or are looking to meet up with friends. Or random stalkers. Whatever.

My crystal ball is broken, so I don’t know if anyone will still care about Twitter in four weeks. Or Monday, for that matter: Twitter has been a bit erratic lately as so many people seem to be trying it out and hammering their servers.
