Absolutely! This site is all you really need. I originally learned just off albums and a couple of songbooks back in the day. I got pretty fluent, but admit I was a bit of a hack, too. Still I could sit and play anything with anyone pretty much.

I subscribe to GuitarTricks as an instructional source and even as a motivator. Sometimes I follow lessons, sometimes I just read the forums. Questions people ask and things they discuss can set me on a path when I'm feeling aimless.

...I wish this kind of thing was around 25 years ago.
