Give a man a fish and feed him for a day....Teach him to use the internet and he won't bother you for weeks!
I've never been a fan of Twitter, but I've always been a big fan of of conceptual artist Jenny Holzer. So I tend to agree with the folks at Boing Boing who point out her alleged Twitter stream with the caveat that she is "the only person who should be allowed to use Twitter."
