Yes. I flirted with the idea of an online community with a half life. For example, every 6 months the URL would completely change and only the top 1% of members would be notified of the new location. It would be in their hands to repopulate the community.

I haven't figured out how to determine the top 1% but this was more a pipe dream a than serious potential project. Anyone is free to take the idea and run with it.

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.
