Right there with you pal. Anxiously waiting to google's APIs. (they are mentioned here http://www.google.com/intl/en/+/policy/)

I can't express how sick i feel doing facebook apps in the past year, it has been nothing but disappointment and anger (but still makes the money due to huge traction).

Google has a much better track record of fostering developer ecosystems and a much better understanding of how to deal with app spam. Hope they do their best to create a good web app ecosystem.
