A dead end in a comments thread. Can apply to any sort of forum where comments are left by users. This can be initiated by an uninvited comment in a thread (thereby disrupting already existing conversation), or a dwindling conversation that neither party knows how to end politely.
Jackie and I were commenting on an old photo of us on Facebook, until Josh interjected with his comment. He led us to a thread end.
