My sister sent me a link to this article in the Washington Post. It's pretty much what I've already written here or linked to but with more statistics and $$ numbers.
I'd like to add though that even though Design Blogs are great, many of them would not exist if not for the print magazines that so many images are pulled from. I also don't really like being tied to watching a computer screen all the time.
So, we still need those mags.
