About the only reason I feel apprehensive about Radio is that it’s too heavy. I develop for a living. My machines are pretty beefy, but I need most of them to be running at top capacity, with no spare cycles going anywhere. In fact, one of the reasons I like MovableType is that it plugs in nicely into an Apache box, not consuming any resources until I’m actually using it. Sigh — one can’t have everything, can one?
