Built with ASP.NET MVC?

ASP.NET MVC? As that's a new one to me I thought I'd look into it.

I've had a quick look around. It looks like they've dropped the runat="server" and postback stuff?

On one of the developer's blogs I found:

"Postback heavy controls won't support postback operations though." Not sure how heavy is heavy.

This looks like effectively a forking of ASP.NET.
