Twitter bios: Don't be a 'rock star guru' By Doug Gross, CNN
"If you're a "zombie aficionado," a "Web marketing guru" or a "social media evangelist," you may be doing Twitter wrong.
"The 160-character Twitter bio, your introduction to the site's nearly 250 million active users, has been called a "postmodern art form" by The New York Times.
"But for most of us, it's a bit simpler than that. It's a digital calling card, a way to sum up our very essence within Twitter's 160-character limit and, presumably, tell people why they might want to follow us."
