Was randomly clicking through the Blogger site (finding the date created link Andy sent me a while ago) and saw suggestions on what to do when your mom finds out about your blog (also, less tongue in cheeck, how not to get fired because of your blog) in the knowledge base.
Good suggestions, but it also highlights the need for more fine grained publishing control (Towards Semi-Permeable Blogging), and (ideally), a concurrent wide adoption of some sort of federated trust infrastructure [this could help to alleviate the comment spam problem. implemented properly, this could retain privacy fairly well, pseudonymity is all that’s required])
