Facebook is deprecating the Graph API Explorer App as of today, and the Profile Expressions Kit will deprecate on October 1. The latter is due to low adoption, Facebook said.

Finally, Facebook is allowing developers to run test queries through the Graph API Explorer App using their own access tokens.

But there are some hints in Facebook’s Graph API code that could indicate otherwise. Lines of code referring to “rssfeeds” have recently started to appear in Facebook’s Graph API code.
