Unless you're already famous (and even if you are), creating an effective bio entry is a great way to attract followers. Nobody wants to follow someone whose bio reads, "I'm just a couch potato with a lot to say" or "I heart 'Dancing with the Stars' and that says it all." Because no, it doesn't say it all. Be creative, clever and intelligent when writing your bio. You want to sum up who you are in a short space, too, so don't go overboard with the prose. This is also a good place to plant URLs to any other sites you're looking to promote, such as your Facebook page or a blog landing page. But don't only include those links. A good mix of clever self-description mixed with your other links is a good bet to get people interested in what you have to say. If you feel like you can't sum up who you are, find a famous quote that does it for you. Someone might just be intrigued by your Timothy Leary or Ben Franklin quotation and give your account a second look.
