One of the problems is that for the most part the only people who play this game are elderly english speaking north americans. Only a tiny amount of foriegners play AH. At 0400 US central time the MA is for all practical purposes empty. Once again the yanks are the only ones pulling their own weight. Africans, eurasians, aussies and pacific islanders and south americans all need to step up and start doing their part!
Also AH is a boutique game, I've played off and on since 1999 and HTC has never seemed bothered by low numbers of subscribers, in fact it seems like they like it that way. That's something forum posters often fail to consider.
