Have a main search engine that will search the infromation and data on all governemnt sites. Sometimes it vague which department has the infromation on a subject. A general search based that uses key-word tag technology would eliminate the user having to navigate multiple government websites to find what they are looking for.
need a subject/content index to the overall structure of gov't web site content....kind of a google for the vast array of gov't info.
Searching gov sites should be as simple as bing.com and google.com
google uncle sam was a great tool for contractors to research without the mess of non-gov info!
