Actually I'd like to add something:
Since you already have a small emphasize on being advertiser friendly: Maybe you'd like to rethink allowing clicking the same ads every day. Right now with so little advertisers aboard I almost feel bad that I am using up the clicks of sites that I do already know. Maybe limit it after the first 2 days so that you can rclick a site already visited only every other day and after another amount of clicks limit it to once per week. Just something to think about.
