Tried to follow all the Twitter bs and couldn't find 5 tech leaders to follow. It just looks like lots of ads. 503 Tweets and 500 look like ads. This is just time consuming stuff. Sorry. I'm not buying into the Twitter stuff.
I've had a Twitter account since the summer of '08. NYT had a short article about how a guy in Egypt had an account--was arrested and tweeted "Arrested". I liked the back-up plan on this and signed up in case my daughter, Ann, who was headed for Ghana needed to let a bunch of folks know right away that she was in danger. Tweeted about 3 times to practice and forgot about it when she returned. End of story.
