A Big List of Sites That Teach You How to Do Stuff

"With all due respect to Kevin Smith, the web is no longer only for complaining about movies. In fact, there are a large number of very helpful sites that teach you how to do things. These are do-it-yourself sites, but we're not talking about building a deck or baking a cake -- the web is full of more general interest sites that give quality instruction on all sorts of fun and useful projects. Including, sometimes, how to build a deck or bake a cake." -- Josh Cantone (Read/WriteWeb)
