Digg was already losing a lot of marketshare before the v4 rollout. The v4 rollout was the nail in the coffin. Also, it still took about a year before Reddit finally surpassed Digg in terms of total users after that. But engagement and depth of user activity plunged immediately, something that is happening to Twitter now. Also Reddit right now too, which is having its own Digg v4 type of event. Both Twitter and Reddit are on the short path to irrelevancy, and their numbers are only held up by "late quitters." Probably more so in the case of Twitter, which is likely in a later stage of that decline. Reddit is likely just a year behind, although its decline is accelerating faster. We'll see which one fails first soon.
