My personal feeling is that it probably does. But the real reason here is that its unlikely that anyone in pmdev is going to sacrifice tuits for it when it is so likely just to be a big PITA, both due to load, and due to the hassle of it all. My bet is that if we did implement it, the vast majority of the user base wouldnt want it enabled. So which is a better use of our time? New features that users cant do themselves or site reinvention of things that users can do themselves quite easily?
