I'm a hardcore developer gone freelance and I'm getting more and more requests for adwords from my clients. I've just started to read up on it, and of course I'm starting with wikipedia and have moved onto the main site now. I wanted to post here if anyone has some tips or some good blog entires that describe how it works. Strategy posts would be awesome.As always, thanks!
