We're having way too much fun live-profiling and optimising Dendrite thanks to the impromptu load test :D Sorry the server bounces a bit, but we're deploying stuff like https://github.com/matrix-org/dendrite/pull/1666

This is a really interesting use of the protocol and looks very cool, congratulations!

I am curious how this experiment fits with the longer term goals for the project. Do you see Matrix as a social media protocol in addition to chat? If so, do you have plans to integrate with the fediverse/speak ActivityPub?

Matrix is a generic realtime data sync protocol, so yes - we always built it with general social media uses in mind as well as chat (as well as VoIP, VR/AR, IoT etc). Hopefully someone will build an ActivityPub bridge now that Cerulean exists! :)

(more importantly, surely we need a HN bridge!)

A week or so ago, you mentioned on HN [1] that Matrix is in a pretty good position to support a Discus-like comment section for personal blogs and articles.

I think something like Cerulean may even be a better idea. It would probably be straightforward to just make every blog post create a corresponding Cerulean/Matrix post and then have a link to it automatically inserted into the bottom of the post.

One question I have, though, is how performant it is to have thousands and thousands of these small Matrix rooms around. Are rooms that lightweight? One for each post seems like it could be a lot, but I'm not familiar with the intended internals for servers to use in how they represent rooms.

yup, rooms are lightweight - not much heavier than just sending a message. I suspect the only reason that people assume they are heavyweight is psychological because in real life rooms are... heavy :)

Totally agreed that turning Cerulean into a Disqus-clone would be awesome; hopefully someone will pick it up and do so!
