An excerpt from the about page, explaining what the goal of the site is:
The goal of WebStandardsSherpa.com is to provide web professionals the opportunity to receive feedback, glean advice and learn best practices from experts in the field to help them improve the quality of their own work.
Web Standards Sherpa came about because we wanted to create a repository of best practices information while, at the same time, providing mentorship opportunities for practicing web professionals.
Dan Cederholm, Founder and Principal of SimpleBits, handled the initial design and art direction of the project which he talks about in a blog post on his site. There are two shots up on Dribble as well.
