Pretty sure given a week or two I could take any one of the many ideas here and have a few prototypes, a web-shop and be ready to take orders... and not have spent much more than most people could comfortably run up on a credit card. And that's without having the skill to actually produce any of them myself.
This is what concerns me about littlekyro's approach, he says his skill is "business" but I'm not getting a very proactive entrepreneurial vibe off any of his posts... it feels like "business skill" might be a euphemism for book-learnt familiarity with corporate business structures, systems, and terms, not the sort of "business skill" that saw people set up successful startups in their spare bedrooms.
Also, this crowd-sourcing of ideas is risky because there's a vast divide between what people will say they'd like and buy, and what people will actually put their hands in their pockets for. I've seen more than a few projects get scuppered by this - everyone will say "Yeah, sure, I'd buy that" until you ask them for their $50 and then it's well uh I dunno, maybe next month...
