I’d really like to know if there is a website filled with free tutorials and articles about graphic design for WEB 2.0 style websites.

Thanks for helping me.
Designing for web 2.0 isn’t like designing every other site, it has some rules I think. Such as light colors, lots of white spaces, colours fadeout in boxes,standard effects, such as reflection, in logo, etc.
Is there such a site explaining how to build a webpage layout and to design graphic elements following the web 2.0 guidelines then?..
