THat's the problem with these types of sites (and the problem with SO), most of the answers and submissions are by people who don't know what they are doing.
I think these sort of sites always need a big disclaimer on every page (PLEASE DO NOT DO THIS IN PRODUCTION CODE). It's the blind leading the blind.
I do find answers that are marked as correct that are no longer the best answer, what i find less of is obviously wrong answers marked as correct
My understanding was that SO is basically the modern day O’Reilly cookbook.
I wouldn't agree with that. However, answers might get outdated.
Hopefully something reasonably organic arises where good answers are upvoted highest. Or there could be a way to mark things as using an old version.
