I like Twitter. It's pretty much designed for people like me... yup, I'm one of those people who vocalises pretty much every thought. It's good for that, whereas a full-scale blog would be a bit redundant given the brevity, frequency and inanity of the entries. I stop short of using it as an IM service though. I have IM services for that.
Hit me up on there if you like, username's the same as here.
