You're probably not a member of a community which has fully adopted it. I also wouldn't impart your judgement so easily without considering what it would be like to enter into a community that had 100% adoption of a service and how you would behave in that instance. I am not saying it's impossible to live without it, but it certainly makes it more difficult and adds friction to your life that could easily be removed by just joining.
