Ancestry.com Infuriates Webmasters and Bloggers
Ancestry.com is harvesting data from many websites and blogs and putting them in their Internet Biographical Collection. When the collection first began showing up, it was a paid premium site (for what was posted freely on the Web elsewhere).
You can keep up with the controversy at AnceStories, CowHampshire, or GeneaMusings. [These links are to specific posts, but I'm sure you can keep up with the controversy at these and other genealogy blogs by going to the main blog.]
There are some historical and genealogical societies and some USGenWeb county sites which may be removing their data from the Rootsweb pages because of this. Rootsweb is owned by Ancestry.com's parent company The Generations Network.
Update (8/29): They've removed the collection for now.
