I absolutely love this design. I’ve tried to accomplish a design like this myself (a site that’s largely a big set of text links) and have fought opposition from management from the client and lost. Makes me very excited to see a solution like this for a government agency. HUZZAH!
From a design standpoint, this is created with the “designing for the scent of information” concept by Jared Spool front and center. Love. This. Site.
