I just started using FB ads for a sports trivia app I launched (http://www.playhattrick.com http://www.playhattrick.com). So far it's been surprisingly good. We had a big surge in downloads and usage today. Both news feed in in-app ads are getting about a 1% CTR which I consider good for FB. It's too early to tell if I can make it profitable. Tying ad clicks to installs and in-app purchases (conversions) is also something I'm still getting the hang of.
