I wonder what this is really about. I think it may be more or less about Twitter trying to bring developers on to expand their developer platform which probably fell flat. I can't speak on other developers but I won't ever build a business on top of Twitter. I would only use their API as a bonus third party integration feature for something like a Marketing SaaS.
On the off chance that anyone from Twitter is reading this: bring back RSS! I already have a mechanism to 'follow' things on the Internet in which I'm interested; I'd be happy to consume feeds from Twitter as well if you played ball.
