Twitter is considering to allow message longest that 140, but I don't think that the problem is the character limit for the kind of interaction of twitter users. There are other problems not so big but that make the user experience not fluent for a simple app like Twitter. Writing posts with more that 140 can potentially get many FB users, nevertheless TW should take care of the its current users. I notice many incoherences of the web app, for instance the top menu, on left where pop/up and navigation are mixed. Second, the mobile app is very wired I receive notifications about message or followers that appears on my notification tabs randomly. In conclusion, I love TW and I'm not a FB user, but I'm honest my twitter timeline is a bunch of Ads and I follow Twitter just because I love the concept of it.
