I have a love/hate relationship with Al's Ramblings, a Brewers blog. Al's a conservative of the Fox/Coulter/Hannity variety, and wastes no opportunity to echo their opinions, but he's got a lot of great insight into our lovable losers in Milwaukee. I don't think there are any higher-profile Brewers bloggers out there, though I'd love to find one with stronger copy editing skills.
Wow, I do wonder if this is really Tommy Lasorda who is blogging. Dodger Thoughts is one hell of a blog. He even scored an interview with Depodesta.
I'll second Dodger Thoughts here. Jon Weisman writes some great stuff. He manages to effectively balance good reporting, moderating of pro-Moneyball vs. anti-Moneyball debate, and personal narrative. Hell, his gameday chats have anywhere from 200-400 comments. Say jasonspaceman did you get a "Ghame Over" shirt?
