This looks like an innvoative resource for people who want to learn the guitar but either can't get to regular lessons or are so painfully shy that the idea of playing even in front of a teacher makes them have to shit!
GuitarSchool.net has over 150 video lessons online to help you learn how to play guitar. They claim to be able to teach you Blues, Rock or Jazz. Registration and a sample lesson are available at the website.
Looks to be a part of the Guitar Center family. I am luke warm on these guys. Some stuff they got, some stuff and you get a HuH? from the 17 yr old wanna be rock God behind the counter.
UPDATE: Just found this alternative site called TruFireTV. They claim to have over 2,500 guitar lesson videos on-line and you can watch your first 100 FREE. Not too bad. The interface is flash so that loses them some points on my book, but the videos seem to be high quality. I didn't have my guitar in hand but what they were saying makes sense. Check it out HERE.
