Twitter about anything

Twitter is a fun new web app, you sign up with a few friends and then you can post using pretty much anything that sends a message on what your doing at the minute. Seems like a great idea, but i have to wonder how long it would be before I got bored and stopped posting...probably five minutes before my friends joined. I love the name though, reminds me of school where if everyone in the room repeatedly said rhubarb, it sounds like theres a real big discussion going on.... wait twitter is a digital version, now i get it!
