Credit to Leonard Jacobs for pointing this out, but here's Mark Blankenship's blog, "The Critical Condition." Mark does, essentially, what I want to do for a living, and I've got no problem admitting that.
Though this should go without saying, as a freelance arts-and-entertainment critic, the tickets (or books, or screeners) that I review are provided, free of charge, by publicists. As should be obvious to anyone regularly reading this site, that does not make me biased, and those interested in an exploration of potential biases I may actually have can look up the tag "metaDRAMA." For FTC reasons, as of December, 2009, I will use the tag "Independent" when reviewing my own purchases.
