I found it hugely useful in the .Net world. With closed source, obscure errors cannot be as easily tracked down, especially when they are not covered by MSDN or a prominent blog. A couple years after switching to an open source stack, I barely use it at all, and when I do finally hit a wall and ask a question, I get an answer ~20% of the time (compared to 90%+ when I was in .Net). I am a huge fan of SO, but good docs and readable code go a lot further.
