> Did anyone actually like StackOverflow?

Absolutely! It answered so many questions I had. I remember when it was relatively new, and I'd just heard about it, it profoundly changed how I found answers to programming questions. Suddenly I could find people having similar problems that I had, who had asked the question, and had actually gotten a useful answer from someone who knew!

It wasn't perfect, of course (nothing is), but it was orders of magnitude better sifting through crap blog posts and confusing reference material. (Not to mention sites like experts-exchange.)
