Five years ago, Stack Overflow launched
StackOverflow took the place of news/dejanews for me. It's a first place to stop whenever I have trouble with just about any piece of software or writing software, usually the answer is right there on the first place in a fairly easy to digest form. Along with wikipedia and the Khan academy it is a fantastic resource.Amazing it is only 5 years old, it feels like it has been around forever, I recall coming across it for the first time while still in Canada and thinking 'this is neat'. I never contributed which is really a miss on my part but I try to keep the number of accounts that I have to an absolute minimum and stackoverflow is plenty useful as it is today. I really should do some community service there one of these days, it is only fair.Hard to imagine that even google could not rescue usenet (or rather, dejanews) from the spam and the trolls.
