I just joined Twitter and am pretty enamored with it. If you haven't heard of it, it's a site where you update what you're currently doing throughout the day in a couple sentences or less. A pretty neat idea. Everytime you update, anyone who is 'following' your profile receives the post on their page. Blogging buddy Eric Orchard has a profile on there as well and he's a very active member (which I hope to be as well).
Come join me!
