Reddit has considerably less engagement because people browse it with more intention. There’s very little paid content, so good creators often go to other platforms, and videos are only concentrated in a few subreddits. This creates an environment where there’s less (though not necessarily worse) content, so there’s no endless scrolling like there is in other social media forms.

Reddit is trying to change this, and working hard to do it, part of why they introduced payment for posting(though the system ain’t much), as well as removing r/all in favor of an algorithmic change. Unfortunately for them, this is them failure to account for their niche in the market… But corporations must grow.
