I haven't used SO that much, so it didn't change much for me. I started in 1990. Best resource was the library. University libraries were best. I learned a ton from typing in those BASIC listings in magazines. When I got a modem, I could find some harder to find info on BBSs, Prodigy, or Compuserve. That was like trying to find a needle in a haystack, though. It took like a year or two for me to find a good reference manual on VGA adapters, for example. Finding a txt file like that was like finding treasure. Now I don't have one main resource. Just Google. The main value I get from SO is debates about best practices on specific topics, e.g. stuff like "fastest way to rip a file into an array of structs in .NET".
