I admit: I still don't see what is all the fuss about Twitter.
Twitter is like a selective (your followers only) shout command of old Moo's, but it seems to me to be a drain on productivity. If you think IM can be bad, well, you haven't seen nothing yet.
But I'm still there trying to get it. I wonder if there is really something to get at all.
For now, I cut my following list to about 30 people who are either close friends, or with whom I work constantly. I've also included a couple of so-called-A-list-bloggers that I read. This and going to the settings page and disabling the @ messages cut down the twittering to an acceptable level.
Lets see how this works out for me.
