That may be - club penguin was part of the list of children browser games at the time providing real time player interaction. I listed it because I imagine that's the one most people in tech know because it got a lot of media attention but I admit I know the least about it. Club penguin limited chat as opposed to habbo hotel and moviestarplanet which had, surprisingly, free style chatting (at least in the non-US versions). These were both from scandinavian companies which had a more liberal attitude. As a result, the player connections were deeper.
