I actually like the idea of a "follow-along" much more intrguing than just another "learn to play guitar" site. With that model you can communicate with your readers on the same level which should go along way trust-wise. Wordpress is a good choice, but I wouldn't spend too much time fiddling around with my own theme. Find a template you like and tweak it a little (header graphic, plugins, etc.). But don't focus too much on the technical side of things, those don't make the difference. Your content does. Good luck with our project Tom
Thanks Tom, I am already working on a skin. It's looks pretty good so far, I will let it get coded soon
Your first niche should be something you're interested in. If you're not knowledgeable in your niche it's not going to work. Don't think about the money right now. Furthermore I don't think at this moment you will find an easy niche.
