I try this with js sample app + twitter auth. I get Error: {"type":"Authentication","status":401,"details":{"message":"OAuth Authentication Failure: invalid oauth_token syntax"}} In the other hand, this could be handy for my news reader app for ipad. This notify of new content? Is this suitable for manage several users, each one with their own rss subscriptions?
