To be fair, most of the value in a government's site should be on access to its services, not on information. The information is usually important enough that everybody wants to replicate it.

That said, I have close access to the people managing one such portal here in Brazil, and I can't even convince them not to use Google Analytics. So, yeah, it would be great if we could make them use simple and clear text on static files. It's just not the most important "great thing" we can accomplish.
