Yeah.. I agree.
The site looks fine, professional, all that good stuff... but what exactly is it that your MVC does? You should provide some sort of demonstration on your site. Then again, I do feel rather ignorant on the subject of MVC.. maybe it's self explanatory if I knew it?
Regardless, you need to demonstrate WHY your framework is good.
Oh, indeed that is all planned. Unfortunately however, the framework is in such early stages that it is difficult at this point in time to show too much functionality.
I guess it does need an overview or roadmap page.
