I think Insider is a great addition to the content offered by GuitarTricks! The audio and video clips add a nice perspective to the written word.

On a less enthusiastic note, I am disappointed that it is only offered in Flash format. I am unwilling to install Flash on any device I own, due to Adobe's ongoing inability to secure the product (google "adobe flash vulnerabilities" to raise your awareness). As a result, it is a rare thing for me to have access to a device that can view the mag. It would be great if you could convince joomag to adopt html5 or some other less vulnerable alternative, or seek an alternative publisher.
