There are a lot of blogs out there, good, bad and indifferent. Some feel they have to write something every day whether they have something to say or not. Some get paid to write. Some blogs have paid sponsors. Some of us just write when we have something we want to share, no schedule.
Casefile Clues is written by Michael John Neill. He writes one a week about his research. Most of the specific issues, like post Civil War immigration, are totally irrelevant to my research but there is something to learn in watching his process as he moves along. He calls it a casestudy.
He doesn't have a staff. His day job is math teacher. There are typos and mistakes and the blog may be late but he always catches up. There are no ads, he has no agenda and he is not pushing any company. I find it a refreshing.
I also really like his genealogy tip of the day at http://genealogytipoftheday.blogspot.com. You can subscribe to those free by RSS feed in your feed reader. They always give you something to think about, probably something you have not thought about, or at least not in that way.
Neill also leads research trips to Salt Lake City and Ft. Wayne and he speaks at genealogy societies.
