How the linux communities compare
The three largest communities hold about 67% of the combined membership, but the rest of the list is far from empty — that is where most of the specialised discussion happens. r/linux and r/linuxquestions are the two busiest, with roughly 50 and 60 new posts a day. Per member, the liveliest is r/linux4noobs: 60 posts a day from 275.7K members — a smaller crowd, but an engaged one. The oldest is r/linux, founded in 2008, and every community here is more than five years old — this is a long-established corner of Reddit.
