Well, I just went to the link you provided and aside from 90% of the ideas being well-intentioned but half-baked, I can't help but notice there are no business ideas. So, to answer your question, no, there aren't. Why would anybody waste time documenting an idea they don't have the inclination to implement? Why don't they have the inclination? Because there's no motivation. Why? Because they realize they can't make money off of it. Hence the only ideas you'll find for "free" on the internet are ideas nobody can figure out how to make any money off of. If they could figure that out, then they would have the inclination and thus, logic indicates that they'd MAKE the time. And keep the idea to themselves, not post it up for all to see and profit off of.
