Maybe, though I think a gradual switch through email might be feasible (see my other comment[1]). Also, if new systems provide a long-form-content-centric experience, that would IMO be a pretty big lure for a good chunk of people. Readwise's original post[2] is pretty compelling in that regard. That wouldn't be enough to get a majority of social media users to switch--but even if new systems are limited to the population of people who read articles instead of just tweets, that wouldn't necessarily be a bad thing ¯\_(ツ)_/¯
