Status Updater Guy/Girl
Status Updater couldn't leave the away message concept back in 2004 with the extinction of AIM. Facebook status isn't meant to update people what you are really doing every hour each day. Acceptable Facebook statuses (word? wtf) are 1. inside jokes, 2. funny lines from movies, 3. funny stories. "Heading to the store with my baby, be back in a little bit!" is never acceptable.

Chatter Guy/Girl
Chatter Guy/Girl won't let you reply to a g.d. wall post without messaging you "hey whats up man?"
