From Fred Wilson’s post about Github:
Tools like StackOverflow (a USV portfolio company) and GitHub allow programmers to see how other programmers have solved similar problems. I was at a hackathon up at Columbia University last weekend and one of the hacks was a development environment that automatically queried StackOverflow and GitHub as you are writing code so that you always have in front of you the answers to the questions you are most likely to ask. The developer who did the hack introduced it by saying something like “programming these days is more about searching than anything else”. That reflects how collaborative the sharing of knowledge has become in the world of software development as a result of these cloud based tools for developers.
