Don't get me wrong, I'll use and probably find some enjoyment in strongholds, and you're right, not everyone wants to socialize in a social game, but the world feels dead, and that is not something that has changed since beta. There is a huge cantina on bar shadda that gets a few quests through it and no more.
The devs wanted to artificially create Orgrimar (sp?) from wow. The station is an interesting idea, but Org naturally became the hangout, it wasn't forced as far as I know. I think creating fun and peaceful locations for players to go would have developed the environment better than the stations
