Mysterious creature that edits or removes old entries on a blog - usually because the entries are embarrassing to the blogger. Longoliers are similar to the Ministry of Truth, in George Orwell's Book 1984, in that they function to falsify history.
Australian journalist and blogger Tim Blair was the first to use "Longoliers" to describe this phenomenon. The term was originally used by author Stephen King to describe beings who devour the past.
Longoliers have been busy in th archives of Little Green Footballs and The Daily Dish as the bloggers have moved from right to left on the political spectrum.
