I think so.  A lot of us have our blogs now and if people don't want to read it, they can skip it altogether.  Some people don't like the "self promotion" of it all - but others would like to get their sites going and readers to see if they're interested.  I know me, Lee, Kosmik and a few others pretty regularly blog.  I don't usually post the entire message on here but it's nice to know if I post a cool update I have a place to put it that people can avoid reading if they're not going to like it in the first place.
