Okay, I jumped on the Twitter bandwagon... now I just have to start using it

And I got on Pownce too... but I haven't really played around with that one either.
@OMD: I can't believe you didn't know what Facebook was yet

I use it, probably a little too much. It's like an addiction in a way - I have to check it at least once, usually multiple times throughout the day. I'm getting better though and not checking so often.
