Why do people use Radio, anyway?

I was getting ready to add a weblog I occasionally read to my list of links, now that the owner supports comments, but as I entered one on a recent topic, I found the edit window was obscuring new lines as I typed them, and then when I submitted, it dropped the whole thing for the lack of an email address.

Bah. Perhaps it’s wonderful from the writer’s side of things, but it’s still a publishing tool. If it’s this hard to interact, why would anyone bother?

MovableType seems to do all I need and the price is right.
