The Blogger service seems to have had a serious system issue in the last few days. They deleted tens of thousands of posts across all blogs using the blogger system and in restoring them they seem to have pushed a number of older posts up the list. At the same time I have been editing the labels on old posts as part of a wider project that is currently ongoing. As a result anything I edited in the last few days got deleted and then restored with yesterday's date. Therefore you may have seen posts from 2006 suddenly popping up again. I have fixed these and hopefully blogger have fixed their system.
