Twitter, which in the past has been accused to treating third-party developers as second-class citizens by basically borrowing their functionality before telling them they're not longer needed, has just announced that there are more than 1 million registered Twitter applications from 750,000 developers.

Also Monday, Twitter, which reportedly is under investigation by the Federal Trade Commission for the way it treats third-party developers, announced a new version of the Twitter Developer Site, which includes discussions, a developer blog, better documentation, improved apps management and an enhanced search engine.

Surely these things are unrelated.
