Facebook one you could just sign into a facebook account (if you have one) get the award and then sign out and never, ever sign back into facebook in our account.
I do agree that more awards would be great. I'm not a fan of some of the other things, but the awards I've always liked. Part of the reason for the lack of them is that there is a great deal of effort involved to create an award, for example:
You have to decide what you want the award to be for, and how this can be implemented and wether you want it for different platforms.
If it's an award that relies on having a specific book in your library it makes it easier as that is a "server side" award, and so the app just consumes the award, the mechanics that unleash it are not in the app. If it's "client side", ie; code needs to go in the app to unleash the award, then it requires us to release an update to the app to make the award live, and unless it's something very, very special, we won't release an app update just for an award, so it'd be rolled into the next scheduled update.
There is also the massive amount of design work for an award. The guys that originally did them spend an awful lot of time on them, serious "designed with love" stuff going on there.
Here's hoping we do see more of them though
Oh, someone noticed my disclaimer

I thought I better put it in
