This is quite reassuring. As a historian and archivist, I value permanence and durabilty. Plus I would really like my writing to stay around for a very long time, so that others may learn about me and what I think. Here is the email I got from the blogger folks.

Thanks for writing in. Blogger will never delete or remove any blog
content unless the blog violates our Terms of Service. We intend to retain
content "forever," even after the author dies. Please let me know if you
have any further questions or concerns, and thanks for using Blogger!
