also re: why keep old posts at all
one idea for keeping all these old posts around is you won't know how these will help research in the future, you may not see a lot of use in a couple of one-off posts on a memesite but maybe anthropologists of the future may be interested in web culture and data mine the site (along with many others probably) for the information they are looking for.
