There was a discussion recently about OAuth, and I just saw this blog posthttp://insanecoding.blogspot.com/2013/03/oauth-great-way-to-cripple-your-api.html (posted on slashdothttp://tech.slashdot.org/story/13/03/22/1439235/a-truckload-of-oauth-issues-that-would-make-any-author-quit) with some heavy criticisms. I am not an expert in OAuth and do not yet have a pro/against position, this is more of an FYI for those interested.
