Your friends will forget that post by summer. The internet keeps it on file forever.

Two different memories are running at once. The people you were performing for have a short one, and whatever you posted will be out of their heads in a few months. The archive does not work that way. It keeps things indefinitely and produces them later, in front of people who never had the context that made it make sense.

Before posting something sharp, ask whether you would be fine explaining it to a stranger in four years with none of the backstory. If not, send it to one person instead.
