Half a question / half a comment.
Should a site like guitartricks be affiliated with sites such as www.guitartips.com.au which is linked by the 'Learn guitar in 30 days' link at the bottom of the page? Sites like this are broadly speaking full of cobblers, and give beginners the wrong impression.
Out of curiousity, I signed up on the guitartips site to the 7 free lessons, and what I received really couldn't be considered a lesson. Yeah, it's free so no problem, I just don't think a site like guitartricks should associate itself in any way with any site offering a 'master guitar in ten minutes' type of mentality.
This particular example to be fair was lower on the BS radar than alot of others, but still - practice is the only way to improve, and 30 days is not a realistic timeline for anything worth 'learning' really.
Just a thought...
