There always those really weird esoteric bugs that someone has already slogged through lots of trial and error to resolve. SO is great for those kinds of problems.
Yep - if you're getting a particular error code or message that makes no sense, googling as often as not finds it in a SO post, along with 20 ways to solve it, of which at least 1 usually gives you what you need to do so. It's hard to imagine how much time I'd have spent tracking it down otherwise.
