what happens is that you can edit and re-edit your fb comments, and, in classic palimpsest fashion, all pre-edited versions are visible to those who choose to look for them. this makes little sense when viewed in a purely practical light - after all, the whole point of editing one's comment is to take away the typo, the heat-of-the-moment angry words, the inappropriate remark, the misspelled name, the pointed slur, the unfinished thought, and substitute the proper spelling, the witty retort, the fully formed and polished sentence that would leave one's mama proud. editing and leaving behind the electronic version of the scribbled, liquid-papered over, ink-stained first draft makes absolutely no sense, unless we see in this the oh so subtle gift of the palimpsest: thoughts layered upon thoughts, inklings half-formed morphing elegantly into fully fledged ideas, philosophical debates with the self resolved, mental disorder, step by step, evolving into cool clear analysis. or you can just insult someone repeatedly as a joke and see if they have the mental wherewithal to discover your hidden arsenal of abuse.
