I do agree that the blogs which show you slices of peoples' lives and their reactions to things like books, movies, etc. are more interesting than those that engage in nonstop political ranting, and that's part of what I like about Mitch's site. It's also why I think I prefer LJ to conventional blogging - there's more of a sense of community on here, I think, and more of the human touch than you're likely to see on a regular blog. Which is why I don't mind so much not being part of the MOB, despite being at a couple of their functions and expressing interest. They're a lot more political than I am, though we have the same views on a lot of stuff. Whatever...I'm too old to be all sad because I'm not in with the in-crowd. *shrugs*
Probably the best point about the other Kevin's post is his advice to his fellow liberals to go a little easier on the ranting and bile. I don't think it's advice that's likely to be followed by a lot of them, but I do think it's encouraging that some on the left are beginning to realize they have a problem.
