David S. Ferriero, Archivist of the United States, writes a very interesting personal blog. This doesn't appear to be written by an anonymous staff member; Ferriero appears to write the articles himself.
In a recent article entitled The Wisdom of the Crowd, he describes a recent crowd-sourced that should benefit genealogists and historians alike. He writes:
On June 15th we launched our tagging feature on the Online Public Access (OPA) prototype in another “citizen archivist” venture. Convinced that our users know a lot about the records we are stewarding, this is an opportunity to contribute that knowledge. As you search the catalog, you are invited to tag any archival description, person, or organization name records with the keywords or labels that are meaningful to you. We expect that crowdsourcing tagging will enhance the quality of the content and make it easier for people to find what they are looking for. A description of this new feature can be found on the NARAtions blog, along with a link to the registration page.
In the first month we have had more than 1,000 tags contributed!
