regarding #1 very often you find out that you or someone else are the last piece in the asking chain, and stackoverflow is not always a solution. the solution is expensive consulting companies that will gladly take your money, but if there was some sort of service that can lower the costs, I think it might work. many companies seek external advise, especially for critical parts or new technologies. there is already an industry of software consulting, and I think it can be disrupted.
