I just saw this (http://www.techphylum.com/2017/02/manjaro-arm-to-shut-down.html) announcement. Funny because I tried Manjaro in the past and thought it was an excellent distro, and had thought of trying it on my RPi. They're shutting down due to lack of maintainers and lack of users, although they'll keep it alive if a few others step up to the plate. My guess is that Raspbian, and perhaps Ubuntu Mate, are by far the dominant all-purpose distros being used on RPi's. I wonder how other RPi distros like Pidora are faring?
