Let’s pretend someone has convinced you to join Facebook. You play along, and at least register for an account. Now what? Whether you’re a business looking to represent yourself inside of Facebook or an individual looking to tap into Facebook for its rich social interactions, here’s a quick list of things to go do.
Put a decent profile picture on there. NOT a professional photo. God, those look like school photos.
Fill out your interests a bit. (I have a hack here: I killed most of the personal info, so that the “Wall” and other apps wasn’t a mile down the page. How do YOU do it?)
Add a few useful apps. I’ve added Flickr, Upcoming, Lijit, Blog Friends, Video, Google Reader, Email Me Instead, and a few more.
Avoid not-so-useful apps (Unless they’re your thing), like zombies, fishbowls, graffiti, etc.
Add friends. Facebook’s nicer if you have people to interact with.
Join a few groups. See if you can contribute.
Update your status message periodically. (This is Facebook’s hint to get you to come back often).
Explore. Why be in a social network if you can’t see what you don’t know?
