My choice this week is The Ancestry Insider, written by an anonymous suspender-clad gentleman with an excellent avatar (it even kind of looks like him!).
The Ancestry Insider provides a unique perspective among genealogy blogs - an insider's look at FamilySearch.org and Ancestry.com. He is currently employed by FamilySearch and was previously employed by Ancestry.com. In addition, he has a computer background and is an LDS church member. That is quite a combination of knowledge and talent, and Mr. AI puts it to good use.
To top it off, Mr AI is a distant cousin of mine - his surname leads back to one of my Massachusetts Bay Colony immigrants. My guess is, that if he made his ancestry known, that we would find several other cousin relationships.
If you are not reading The Ancestry Insider blog, I recommend that you add it to your RSS feed, blog reader, or Favorites/Bookmarks and visit the site often.
