I don't GAF about that. But since we have these conversations every month I can't help but see that you're willfully blind to anything that you aren't yourself interested in. If you believe in generational changeover as a driving force, then own it. Apply the logic consistently. Ie if you really believe that the reason you were wrong all these years about comic art prices is due to those kids growing up, then you ought to be quite bullish on video games, mtg, and pokemon.
But, since you'll never admit to that, I'm forced to think that you're full of poop when you say you've learned anything from it.
