I exclusively use new Reddit. The increased friction around every single interaction is great for limiting the amount of time I spend there: it raises the bar for deciding to actually view a discussion, and the incomprehensible nesting-collapse algorithm keeps me from going down rabbit holes in threads unless it's something that genuinely interests me.

It's similar to my YouTube usage. All the pre-roll ads ensure I only start videos I'm reasonably sure I'll want to watch, and mid-rolls are a perfect reminder to bail if I'm not fully invested in what I'm watching.
