People have been predicting the doom of this website since at least 2005. The HD playership may ebb and flow, but I don't foresee them shutting down the game at all...this is one of their bigger money makers I think, which may not be saying much though either.
There's no real way to combat being burned out. Usually if I coach 2 teams for too long, I start to tire of the game (though I've done it for much of the last year or so, but it is wearing on me a bit, especially since I haven't reached D1 yet). I can't believe some guys on here coach 4, 8, 10 teams at a time...especially 7 teams in game-a-day worlds....that would burn me the hell out in no time.
My best advice to new users in HD is to have the guts to stick around and become successful here...it isn't like a console game where you pick it up, play a season and win the national championship...there's a lot of learning/strategizing involved, friend/foe making, and this is the best college basketball of any kind, anywhere ever, so I hope that all the newbs give this thing an honest go.
HD/WIS is poorly advertised, but maybe the market just isn't there. Personally I feel like not a lot of people know about it. Despite my rambling, I think HD will continue basically forever, regardless. It sucks losing guys like billyg because you come to enjoy them not only in the game, but in the forums as well, sitemails perhaps. With that said, I don't want HD to lose its personalities it has here on the boards. A chatter-less message board would tune me out as well I think. K that's it...filibustering 101 lol.
