At the recent WSGS conference David Rencher said that Family Search was adding about a million new names, and I can not remember if that was a day or a week, but still it is a lot of new names to research, and to come back often to see if the name you are researching is there now. He also said he gets reports telling him what new data is being added, but how does the average genealogist find out what is being added? The answer is blogs! I know several of the blogs I read using Feedly list the updated list almost weekly. I will just list three here, the first one is a Washington resident Leland Meitzler in his GenaelogyBlog . The second is Randy Seaver with his GeneaMusings Blog. Randy also lists the new or updated lists on Ancestry. The last one is Renee Zamora, and she lists a lot of happenings at Family Search, like the call for 100,000 volunteers to index records  or to beta test the new Family Search Home Page
