I am sur eyou precisely meant add 3 articles PER DAY unless you want Google and the world to belief that you are a hobby site ...
studying what exactly? please be more specific on your post. i suggest you to put ad at content to blend with the site ,that way you can get higher amount of clicks.
dcoops, Maybe give adsense some time to renew the ads. It could take some time, although I really don't know how much; maybe someone else could tell us. Have you thought about putting adsense in the first slot of the page? I would do that for sure, if it's possible in Wordpress. And listen to hans, the more content, the better! Although I'm having a hard time myself adding articles, as English isn't my native language and I want the articles to be perfect... Good luck dcoops, and thanks for keeping us updated.
