If you use Blogger or Blogspot, you owe something to Evan Williams. He demonstrated and discussed Blogger briefly. He wasn't given much time, and somehow the issue of Blogspot downtime didn't come up... Anyway, he and host Chris Pirillo (also a blogger) briefly discussed these blogs:
b-may.com - Olympics news and more
satn.org - Bob Frankston - I'm not worthy, I'm not worthy!
lightningfield.com - many photos
Later in the show Cat Schwartz mentioned a cooking blog, the Red Kitchen. People post recipes, and you can comment on them.
Or check out the Call for Help website for another list of interesting blogs.
But before you do that, check out the many worthy blogs I've permalinked on the left.
