Of course they have lots of themes, and keep them pretty fresh. It looks like a couple of basic templates, with various design interpretations. The habitat theme is appealing because I’m looking for something that would serve as a minimal design. And yes it has my “edit this” feature, plus it’s advertised as widget ready, although the headers are suppressed. The “habitat” lettering picks up your blog name. And come to think of it, offering a free theme is a kind of habitat service to fellow bloggers.
