A lot of tweets have no value without context and many times that context can simply be timing. This is especially true during live events like the Superbowl or Oscars. Those tweets might have immense immediate value, but they lose almost all value once that live event has passed. If you want a perfectly currated feed that allows users to go back and read your tweet history (or you expect someone might do that as part of a hiring decision) I could certainly see value in clearing out those tweets that are now worthless without their original context.

I follow your point, but isn't that the duality of what hashtags try to solve (topic and context)?
