I'm not sure how used the Download are is but I thought I'd give a couple of suggestions that I would like to see.
-For the download rating - it would be nice to know how many people voted (eg: 4 out of 10 by 3 people)
-A comment/thread discussion area? I'd like to know what people have to say about a particular piece of software (eg AntiVirus) compared to what my peers think/experience.
That's my suggestions, but like I said, I don't know how much use that part of AO gets and if it's worth implementing.
