Of the 35 friends of mine who bought this game, I think only 3 are even bothering to log in anymore. If that's a litmus test for activity in a broad sense, I think people have just realized there's basically nothing to do in the game. It's essentially a very early beta with no content, and even then most of the stuff doesn't work, there's long server outages, tons of lag, and broken mechanics that make PvP impossible.

I think the better question is: "Why did you even log in to go look for people?" It's not like you can do anything with them once you find them.
