I don't feel you are really learning anything from this site. It's more like a collection of cheat sheets.
I’ve been programming for 15+ years, everything from assembly to the latest JS. I don’t need a $50 book for, say, C# that is targeted at everyone and so spends time explaining basic programming concepts. I need a 10,000 foot view and then I can drill down into the things that are unique or otherwise unclear.
