Although SSC/ACX has decreased in importance, I think it still recruited most of its respondents relatively late (partly due to starting later than other sources). e.g. SSC’s peak was in 2017, but TED Talks recruited their most respondents in 2013 (mean years in EA for SSC = 3.8, mean years in EA for Ted Talk = 4.78). The case is more clear for podcasts (mean years in EA = 2.59).
That said, there was some evidence from last year’s EAS of SSC respondents being lower engagement even in a model controlling for time in EA.
