The time is nigh, my friends. The momentum has been building for the latest buzz word in the industry, "responsive design," but hardly anyone is putting it to use. I think that's partially because it goes against traditional web design practices, but mostly because it's harder. It will just flat out take longer to design and develop responsive websites.
Because more than anything, web design is about asking the right questions. And really, that's what responsive web design is: a possible solution, a way to more fully design for the web's inherent flexibility.
