This seems a little mean-spirited – though unintentionally, I would assume.
Today, Twitter designer Andrea Conway has shared a new mock-up of a possible functionality that would enable users to set a notification to be reminded of a specific tweet, anywhere from an hour to a year in advance.
Which could be handy, as there’s a range of instances where someone, say, tweets something about a sports team or event, and you might want to keep tabs on that for later reference.
