If you want to be hit over the head with great design work then you should head to Dribbble at least once every few days. Head to the Popular section to see what the community has voted as the best designs for that day, or search for things like "icon" or "iPhone" to see a wealth of not just great work, but also people that you can contract design work out to. I'm a designer and I think most of my inspiration now comes from browsing Dribbble.
(Also, I think all of the screenshots in the original article were originally posted on Dribbble.)
