I'm fairly confident that the new reddit React implementation can be improved in performance by a factor of 3x to 10x. I would be interested to hear others who have good reason to explain why not. I can certainly imagine React-like systems that are capable of statically determining DOM influence sufficient to make comment-collapsing negligible.

It is blatantly obvious to anyone with just a little bit of experience that the reddit devs barely know what they are doing. This applies to their frontend as well as backend. For some reason, reddit is also the only major social network where downtime is expected. Reddit throwing 500 errors under load happens literally every week.

Presumably the mobile apps works better; they don’t care very much about the website because they want to push everyone to the app anyway.

Reddit also puts the "eventually" in "eventually consistent". Not in the sense of consistency being driven by events, but in the colloquial sense of "someday". The new message indicator will go away ... eventually. Your comment will show up ... eventually.
