@twitter for 2 weeks now

Been twitting (or is it tweating (twatting??)) for 2 weeks now and I really like it. Its a decent middle ground between instant messenger and and a blog. Its very cool to be able to interact with people who you otherwise would have no way of contacting. I don't enjoy really bsing all day on instant messengers I think it will be a cool tool to use for contests.... and yes we will have more contests. Probably late April early may. I plan on taking a short vacation after the Elite Retreat. I am actually kind of surprised more affiliate & CPA companies do not use it as a tool to let their affiliates know of new deals... especially 0second ones. Anyway how do you describe twitter to those who have never used it?
