If you are working in a company, sometimes your colleagues may be better than stack overflow. Sometimes it is good not to reinvent wheel while beginning a product. There may be great articles about the architectures , gang of four principles bla bla . It may tempt you to rewrite entire codebase.Sometimes you have to stick to the deadlines while solving a problem. Solution from your colleagues may not be technical one but he may have the blind solutions to the problems that your product is currently facing which you can't even stackoverflow.
When your free stackoverflow , when you are in hurry colleague overflow :-P
