I don't know, I found the learning curve on Reddit very weird. In so many ways, it was just a real downgrade from what I was used to, at least with respect to the actual design. But then, I think the switch to flat forum layouts (eg things like Discourse) was a huge step backwards, and having that, but also a bazillion of them in the same place, and a flat view that shuffled them all together just seemed overwhelming and impossible to navigate.

Going from that to "that, but they're different websites again" honestly feels less confusing to me.
