Literally 90% of the guitar skills I've gained in the last 5-6 years was from here. I just find some songs I wanna learn and then find the tab, learn whatever chords I don't already know, play, and then repeat with the next song. I've got enough knowledge now to seem like I took classes in a discussion but I still can't read sheet music or know anything about scales or anything. Don't plan on it either.

If you would know the basics of reading chords, I would suggest www.guitartabs.cc
Really a great source for learning hard core strings.
