Ryan wrote about Twitter, and I got intrigued enough to sign up myself.
I rather like this idea. For all the Voxes, Diggs, del.icio.us.es, Last.fms and MySpaces out there, a site that forces its users to be concise is a rare thing. There have been many times I wish my long-winded online journal wouldn’t look so awkward with just a single-line entry. Twitter lets me braindump without having to be literate about it.
The social aspect of Twitter, however, lends itself to being an extension of instant messaging, which I guess it would since it can plug into IM and mobile devices. The resulting dialog often looks like an IRC chat done entirely with /me commands.
I would like a friend search, though. Friends of mine could have signed up for the site, but I wouldn’t know it unless they announced their presence.
Twitter is an interesting site, compact but wide open.
