I have to agree with GovLoop in saying give it some more time. I think this is going to be something that has to grow and evolve and we'll see results over time.
One thing that I've seen suggested on other blogs and I would have to agree with would be the consolidation of some of the websites. Too many times it becomes difficult to find things and people end up going from one govt website to another...when it would be far simpler to do a big umbrella-type website and group alot of the websites under one, with links to many others. I'm not an IT person, so maybe this is not a do-able thing but it would make it easier for users.
