I don't really follow any text based blogs, but I do follow the video blogs, or vlogs for short. Some of my faves:
http://www.youtube.com/user/grishno (Grishno keeps it pretty real and down to earth, and documents her progress from day 1 one)
http://www.youtube.com/watch?v=bjstrpjUkc8 (Jesslyn has a fairly short history on youtube, but she's another who's documented her progress.)
http://www.youtube.com/user/moonfire1777 (Just found MoonFire, but she seems like she's a good success story and educational to boot)
