I just stumbled upon these threads, and I'd like to sign up. I sent Max an e-mail, but it sounds like he's tied up with his own non-internet life.
My niche (if Max let's me sign-up for this project) would be money management for recent college grads. I'm still going to look further, but it looks like the best available site name is
www.moneyaftercollege.com
I'm a complete noob to all this but look forward to learning and helping others succeed. I chose this niche because it's something that i could easily write articles about, and although a lot of the big money management websites have sections geared towards young people, I think there's actually a chance for me to fit in because it looks like there aren't too many dedicated sites to the topic. The main dedicated site for recent grads is
www.youngmoney.com.
Feedback is always welcome...
