Like the moms at Roxie's World, I used to read BitchPhD in the early days when it seemed like one earnest, passionate voice, and I sort of trailed off when it became a group blog, not because the group bloggers were less earnest but because I missed that original voice. If I think about what draws me into reading blogs, it's the voice of the blogger.
Now, at BitchPhD, I found a lot of good stuff, although sometimes I felt as though I were being told the One Best Way to be a feminist. Sometimes I agreed, and sometimes I didn't. But that's the point, with a blog: if a blogger doesn't care about what he or she is writing, what's the point of blogging? I'm not talking about writers' blogs that are really press releases (here's my itinerary for the latest press junket, and here's a picture of my book with a convenient link), but blogs written primarily not for commercial purposes. You can disagree, but you don't doubt that the person cares.
There are a lot of great new blogs now (see blogroll!), but I'm thinking of blogs that have shut down over the past few years whose voices I miss. Mel at In Favor of Thinking would be one, especially her post on grading championships. MaggieMay (and her stories) would be one, and JustTenured would be another. Dr. Brazen Hussy just shut down recently, which leaves entirely open the Angry Bird Banding section of the blogosphere, among other things. There are others, too, whose blog titles I can't remember but whose voices I can.
I guess if this were a banquet, I'd raise a virtual glass to those bloggers.
