How does the "players met" section in the playstation network menu work?

yes, the people you meet online in a game, on xbox live it goes back for about 2 weeks, i dont know about that on PSN

the list doesn’t seem nearly long enough to go back two weeks. I’d say there’s less than a hundred on there, and I play a lot. Even though I’m a ps3 person, xbl does seem to have it’s networking a lot more together.

I think its a number instead of a time limit, but after a certian offline time it deletes itself.
