We had the pleasure of doing the end-user citizen UX (usability and IA) research for the City of Austin's completely redone website. Steel Advertising and Interactive did the design and knocked it out of the park.
Check out the City of Austin website here.
And the MuniNetGuide article here. Where they state "To say Austin's revamped municipal website is "impressive" is like calling a giraffe a tall animal." Read it and see why usability research pays big dividends!
