I wonder if there is a better way to break up the parts of brid.gy. It might make more sense to have brid.gy backfeed separate from brid.gy POSSE separate from brid.gy PESOS. Then it becomes an a-la cart solution. Someone maybe could handle all their own publishing but just notify brid.gy which posts to watch (after their syndication links have been added).
In any case, I like to think that the speed issue will go away in the future. Once indieweb readers really start, that's when we would hopefully get those one-click like buttons etc.
