There's sub reddit[1] i tried for some time , but didn't really stick to it. The hard part here is building a community of people who will contribute problems and content around problems. This might be bootstrapped at the beginning either by putting effort in searching the web for such problems, and asking experts around the web about problems, and slowly building a database. Such content could be a pull for some groups of people, many of them will be more interested in solutions ,but some will be a source of more problems. And there's also the question of exposing the information in such a way to encourage innovation and not just reading.Not sure what the right way to do this, but it's interesting. It's not easy to create a high quality content/community site around this , but when solved well this could be a really valuable site.
