The word has been making the rounds about the new usa.gov genealogy page, which includes links for family history and genealogy research info for all 50 states. Each link leads toward a single resource page providing general overviews of resources available for the state in question. The state-specific resource pages are hosted by particular organizations, such as state libraries and historical societies.
For instance, the California link goes to a page outlining some resources available at the California State Library, and links to their Guide to Sources for Genealogy.
I found some interesting resources I was unaware of in some of the states I research, so the links are worth checking out even for "old hand" states. After all, resources are constantly coming online, and it's always worth checking out what's new!
