......Learning Linux Debian is a nice hobby(feels more like a lifestyle)
Linux always felt larger than merely another OS, whether Debian or other. IMO that's because of the free-software movement's stated social goals and because of the broad cooperation needed to make the software. Yet the free-software movement is unknown to the humans who rely on Linux servers as only infrastructure, and mostly ignored as a social movement even by those who use Linux consciously or with economic intent.
