On the previous post, I outlined how you can set up a microblogging site using Buddypress. Note that I didn't specify on what Wordpress variant, as in Wordpress MU or the single user version. Well, since I installed the plugin on the single user site I see no problem if used on your personal blog (wrong?).
But here is one thread from the Buddypress Forums that is....: Installing Buddypress. And the jury is out.
