After doing Django for 5 years, the nail in the coffin was when I wanted to simply access a users me object from their facebook graph timeline. Riddle me that. In ruby-pragmatism land it's a gem and a line or two of code away, thanks to the awesome Koala library.
Kenneth Reitz's recent requests library is the first refreshing and pragmatic python tool I have seen in a long time. This oauth library shares the same friendly and straightforward interface too. The docs and examples are directly clear and directly in front of you. It's simple and pragmatic.
The stars on the repo's speak for themselves ... rauth has over 700 stars, whereas oauthlib has considerably less than half of that. I'm not trying to tell you that you suck, because I admire your work quite a lot, but I think these days developers want simple and pragmatic.
