There was a time when we were all pleased to learn the ropes, Rarely would anybody state that their particular domain was brilliant, ideal for ...etc. It was so much more fun when just about everyone was on the learning curve (apart from a few old-timers - who gave their advice so freely) I think we all recognized this was going to take years of heartbreak, occasional windfalls to just about balance our losses.
But today most see themselves as instant experts. Just look at the references to absurd valuation, they are quoted almost every listing. Those poor old multi-million/billion dollar businesses just don't know what they're missing. If only I could get them to recognize my genius. No wonder most of the real old-hands stay away from the boards these days - It just isn't worth the pain of being honest.
Ultimately they all fall by the wayside but not before they have vented their disdain at anybody who dared question their logic.
