The Linux kernel as a whole is developed by people who rarely see each other in person, but there are several caveats that make it hard to generalize from that. * Individual parts of the Linux kernel are often developed by people who do work together in an office (e.g. I used to sit with a bunch at Red Hat). * Top-level Linux folks do meet in person fairly regularly, especially at LF events. * Collaboration via email etc. is the primary workflow for the kernel, so there's no in-office cabal that has to learn new habits (and likely will resist doing so). I'm also tired of hearing how silly startups can't do remote, but I don't think I'd hold up the kernel as an example that they could/should emulate.
