I think this is a fun idea. People who run sites like reddit or HN or fark are attempting to make themselves middlemen to advance various of their interests. As a user I don't lose very much by finding one cool link on reddit and another on HN. To me it is just another url. But if a prolific respected user of HN migrates fo a new place, that probably causes the proprietor of HN more pain than the users of HN. Because unless you are for some reason confining yourself to the ghetto that is HN, you most likely are looking in a few different places for your enlightenment. A community with a fuse, as it were, would be quite healthy.
