I have no clue why you'd build an app on Twitter's API anymore. I get it from their perspective (they want to control the ecosystem completely), however they've made it clear they don't care about anyone developing on them. Which is sad, since they only exist thanks to their early community of developers.
I can't believe they killed off their MacOS Twitter app, told people to use third-party apps, and now are effectively killing them off too.
(All this being said... Twitter is ripe for abuse, and locking down their API is probably one of the best ways to fix this)
