Some change frequently and others do not. High on my list are those that keep me informed of web pages, changes in the large genealogy databases on Internet and unique places on Internet for the genealogist.
The Ancestry Insider is one of my favorites. He keeps readers informed about FamilySearch and Ancestry.com issues and most recently recommendations on using NARA in Washington, DC.
Rainy Day Genealogy Readings doesn't have to read just on rainy days. If you live in arid country, you might miss all of the blog! This contains very interesting and unique ideas for research on Internet.
Since I use a Mac, I enjoy reading the MacGenealogist.com blog. It is informative not only for Reunion, but other genealogy software for the Macintosh. His almost daily videos are easy to follow and understand.
If you are looking for free Internet web pages, be sure to read Free Genealogy. This is updated daily and contains many worthwhile links.
It is important to go back through archives on all of these sites. Then you will learn what has been posted and be caught up to speed.
Happy blogging ... morning, afternoon or evening!
