All the MoQ articles have such a good writing style, I read them every time a new one gets posted on here. It makes me kind of sad I have no excuse to use it for anything...
MoQ is “Media over QUIC,” although I suspect it’ll eventually go the npm path and just end up being MoQ means MoQ.
Depending on the use case you could think of it as an alternative to WebRTC with lower level control, but honestly it’s a lot more open ended than that.
