Facebook announced on Tuesday on their developer blog  that they will release a subscription service for app developers. This doesn’t mean that you’ll have to pay to use an app on facebook however you may have to pay a subscription fee on applications if  an application maker enables it on there application you may have to pay a fee to access and use the app.

Facebook also stated that they will soon be releasing local currency changes to users. This means instead of purchasing 8 INR worth of Facebook credits for it to be changed to USD currency will not be converted and stay at INR (or whatever your local currency is).

Although these features are to be released sometime in july Facebook has already started testing these services with Zynga and Kixeye. Zynga and Kixeye are two of the most used application owners and developers.

The subscription services is another way for Facebook to earn an income other than from investors,share holders and advertisers. Last year Facebook derived about 83% of its 3.7 billion in revenue from its advertising platform and the rest primarily from Zynga purchasing goods and services from Facebook.
