It will never have the one thing that people come to Reddit for right? NSFW. Not porn precisely, but a range of freedom of expression that goes beyond the narrow band of expression allowed on Zuck’s platforms.

It does look like more of a hybrid between Twitter and Reddit with the threaded conversations and nerd-friendly API layer i.e. ActivityPub.
