People have been buying established businesses and improving them and profiting for a very long time, so whilst the "entrepreneurial spirit" doesn't sort of feel right with buying ideas, it is certainly a viable idea. Delivering a basic upvoting type system for ideas would probably be interesting to a lot of people. Getting good ideas out of people (especially for free) could be difficult, and finding a way of getting only positive feedback (comments etc) on ideas also difficult (working on the assumption that you want ideas from the public rather than just from an internal team), but solving difficult problems is what it is all about! I've passed on a lot of ideas that I have had because I don't believe they could make enough money to be viable for me (I live in an expensive country etc) but having an income of a couple of grand a month might appeal to a lot of people in other situations and those ideas could be useful for them.
