This thing again? Every patent expert I've talked to has told me this is just a bait to lure developers to Twitter: the language is so broad that Twitter's IPA is no different than others. If you look at GitHub you can see that the relevant commits and issues raised have been ignored or dismissed with "it's your opinion against mine". No wonder the repo has been silent for months. I really like the idea but, at patent law teaches us, ideas are worth nothing without execution.
