Facebook users are interesting. We’ve come to know them very well. Our users are adamant, bored, and expressive. Unfortunately, most developers don’t seem to understand how people use Facebook.
The profile is a spring board from which stuff bounces in or out. Most people think it’s just a place to house information, like a Netvibes or a MyYahoo. If you can understand that a profile is about the user, and not who won the baseball game last night, you’re already one step in front of the crowd.
