i thought of another possible real benefit of ads (again remember they would only normally be shown to non-members), which is that as more authors join the site, any ad revenue on their pages can go directly to them, so this could potentially offer a way to share some revenue more easily with other coders. same thing with reviewers - im quite willing to have any ad revenue from review pages go to the reviewer - and this could really be a nice way to suplement any donations that a reviewer would be likely to get. this could be a really nice thing actually.
