Its GetJar Rewards now. For EVERY app you download through them, they give you 10 coins which you can spend on apps. There are a few paid apps that sell through GetJar, mostly themes, but there are a few useful ones like Easy Voice Recorder. Also GetJar now works like AppBrain, where it just serves as a front end for the Android Market, and going through the GetJar app still takes you to PlayStore to download, the difference being GetJar registers you went through them.
Personally, since I won't pay for something as inane as a theme going through GetJar to buy those things is fine by me.
