Does this concern anyone else?
jwecker: As they say in Samoa, fai fai le mu (:  Relax.  Sites evolve and change.  Small towns get bigger.  Eventually you become an old man who yells at neighborhood kids for walking on the lawn.  Before you get to that stage, enjoy the fact that these systems evolve, and for every one that gets too big for your own personal tastes, there are a multitude of smaller ones.  And then there are even your network of actual friends.  Take it easy (:
