There are so many good architecture and design blogs I have stumbled upon, it is difficult to know which one to follow. (And it also makes me wonder why I would subscribe to magazines covering the same topics.)
One I recently liked is CubeMe. It had alot of good posts, including one of this incredible museum planned for Qatar.
For more on the Museum of Modern Arab Art and other interesting design/architecture, see CubeMe.

Its amazing how the museum blends in with the environment. It looks like large sand dunes. I thinks its a very interesting design.
