#12I'm curious of the 2021 measure of total disk space that Discord consumes. Servers that I'm in share images every few minutes, which must add up pretty quick.
Unique images or just copied from elsewhere?

#13TLDR MongoDB then Cassandra
Did they make the move to ScyllaDB, as mentioned in their "Future work" section?
Their jobs pages (e.g. [0]) mention "ScyllaDB/Cassandra".

#14Discord had like $300M invested and they created unparalleled piece of software that ate whole market, damn. One of the most impressive softwares that I've seen and use after years of using ventrilo/mumble/teamspeak.
Well it solved a lot of pain points with the target market.
I remember my friends and I kept bickering who would pay for this month's bill for the vent/mumble servers. That kept on for years until I had enough and hosted my own in a droplet in digital ocean. None of my friends knew how to do that since they're not very technical.
Discord you just had to click a couple buttons and its free.

> ventrilo/mumble/teamspeak To be fair, Mumble is FOSS, and Ventrilo and Teamspeak have literally not iterated since 2005. Discord is pretty mediocre software (remember when they accidentally allowed iframe XSS RCE attacks? A very amateurish mistake), but the incumbents were an absolute dumpster fire.

True, but to be fair: the next iteration of Teamspeak will be based on the Matrix protocol, which is quite a big iteration. See https://news.ycombinator.com/item?id=25743874 .
