i was thinking about this earlier.
more and more, there are paid themes. its hard to find a decent theme that isn't paid anymore. so could there be a sub category for theme reviews or something? someone could rate the various aspects of the theme including icons, sounds, UI images, etc. so others would know generally what a theme is like before they buy it.

Of course, there would have to be strict guidelines, like no bashing, etc.

But thats just me. what do others think?
