It's mostly hobbyist Plan 9 software development. There is some shared disk storage and people upload code they are working on for other people to test and help with, so it is an active workspace for Plan 9 development. There is also a lot of general discussion of computer related topics in the chat, sometimes with a rather abstract mathematical focus on limits of computation and dependent type theories and the logic of infinity, with only a vague connection to existing Plan 9 software - far out brainstorming.
