I've had no formal training with an instructor in a face to face setting. 98% of everything I've learned I've learned here. As mentioned, the site does a great job of organizing lesson plans. You start at the very beginning at guitar fundamentals 1 and 2, then branch off to either Rock, Country, Blues...

It's self paced so there is no rushing you through. There is a great support form where you can post questions directly to individual instructors. You will learn a LOT.

To be fair though, I wouldn't mind having some face to face time with an instructor but mostly just so they can watch what I'm doing and see what bad habits I might need to work on.
