This is getting to be ridiculous (if the story is true). This use case of finding friends wasn't part of the Forbidden Twitter Quadrant, the one containing clients and apps like Favstar. In fact, they encouraged this kind of use at their developer event I attended last year, and of course they would, it strengthens the value of their network. I have been planning this kind of integration myself, but it's beginning to feel like Twitter wants to become a completely isolated silo.
I can only hope a mistake was made here as it sounds so absurd.
