People are either interested or they're not. Ads won't change that.
Though they won't show any interest in it at all if they don't know about it...

Advertisement = more traffic = more income from the ads we host. However, advertising usually isn't free. It's up to our owner to decide when, where and if it's worth it.

As far as whether it would make the site better:
We would get more uploaders and commenters, both the good and the bad. More work for staff in the short term (banning, deleting, checking, teaching). It's difficult to say whether we'd get all that much more quality content. I like to think that our current uploaders are finding most of it, but I have no way to know. Though there's a good chance we'd get more regulars that would make the extra work worth while.
