I like it. Free is attractive. I think this will be a very profitable website for you if you manage it correctly. SEO is going to be the key. It will be easy to get it to page #1 in the search engine.
I really like the Logo design, and the green graphic link buttons.. (on the right and left side of the page). But yes, as others have said, content is a bit bare. :-/ Otherwise really good stuff, keep it up!
The concept of the website is quite ingenious. Also the domain name is a good choice. The contents are written very well and convincing. The layout makes the site easy to navigate. However the graphics need to be polished up. The site needs a professionally designed logo and banner. Basically the graphics as they are now make the site look amateur.
I haven't seen too many Google sites. Why did you go for that option? I would probably remove the stats, as it's not really relevant for your target market to know that.
Website might need some color changes, if trying to build a list you could offer a report and place optin box above the fold.
Honestly, the website is really lacking in my opinion. The web design needs to be more "web2.0" and it looks bland overall.
