It feels a lot more snappy, clean, and modern. I think most of that is because it hasn’t accumulated a lot of the bloat and feature creep that Reddit has over the years. The biggest downside, though, is that the community is much smaller and there isn’t a lot of the niche content that Reddit is so good for.
The great news is that infrastructure to make cities more walkable and bikeable is actually really cheap. Like, compared to car infrastructure that can move a similar amount of people it’s nothing. It’s mostly an issue of political will to actually build the stuff.
