Site needs IA more than design
This new site design is beautiful; it’s impressive for a government page. I feel like the design isn’t really the issue though. The information on the site is still poorly organized, and seems to assume you understand the government lingo the FCC works under. I think the FCC should consider reworking the site to focus on helping the public understand and navigate the issues the FCC deals with, and not on a flashy “web 2.0” look.

How many of your users contributed to this redesign? My guess is not many. Obtain a proper sample of your users, identify what is not working per their input and FIX it. Don't fix what is not broken. The old website was not broken. The new one is.

Dan's right, but look for someone who uses content strategy in their approach to developing that information. You need to work from the bottom up, reviewing content in terms of the purpose it serves. Be sure that each audience you serve has a clear destination page on your site and that each program's content is parceled out in ways that ensure that each audience can get whatever that program has that it needs — without having to filter through a bunch of the rest of that program's content that, to that audience, is simply noise.
It isn't an overnight thing. But real improvement won't start at the top. And do whatever it takes to disabuse whoever it is that loves Flash animations on your home page that they don't meet the needs of the people who use the FCC's website.
