Daniel Mosquin is a working scientist. He maintains a wonderful blog Botany Photo of the Day. The blog contains science. It ranks at 35 on the Technorati scheme that Nature used to puff the top 50 science blogs. But it isn't in that list. I confess. I didn't notice. And Daniel is very magnanimous about being left off the list: "Ah well," he writes, "I still recommend visiting the science weblogs on the list -- many gems in there."
