Google. I was starting my first kit batch (in 15-20 years? unless Mr. Beer doesn't count) and I was looking for details about the boiling process. I found (of course) many sites with relevant info, but the obvious knowledge and the cordiality of the members here immediately attracted me, and all of my subsequent searches throughout my first brew (and beyond) started at the top of this page only! I've probably done a couple dozen searches for various homebrew info and I'm only 3 days into this journey! Glad to beer here!
