Blogs galore

Does anyone know of other 'blog' sites out there? We have explored lots of stuff through the Learning 2.0, but I was intrigued the other day to see other 'blog' sites.... like Blogtown, and Wordpress, on which Blogtown is based....
I also don't know enough about other places such as LiveJournal.
All interesting and with their own rules and ways of getting one's daily grind into the ether capacious.....
Quite interesting - "messing about in blogs".
