More on microblogging trends at ReadWriteWeb State of the Blogosphere 2008.
From the comments:
People write where they hope and believe they have an audience to listen and possibly respond to their thoughts. i.e vanity of the blogger
Right now the audience is now on Twitter and/or Facebook/Friendfeed, so that is where the conversation has moved. In the future it may move to video e.g Seesmic, Qik, Kyte
So that's where the party's gone?
Funnily enough, I've always been a micro tumberly twitterly link blogger, so I may have to start writing long posts to stay well in the nichey-kitchen at parties.
