TL;DR: one of your favorite twitter clients doesn't see most of this being a problem for a couple years --- and even then, they imagine there will possible routes for them to take when that time comes.

It doesn't acknowledge the worry of newcomer developers to the twitter ecosystem, but I feel that we've been doing a good enough job of speaking to the doom and gloom here on HN. (Edit: See lukifer's comment. Excellent example of one of the difficulties that new apps will face)
