I'm not a member but one thing that's kind of interesting is having a rootless, shell-based community. We have this at work on our jumphosts and it's generally a Good Thing. Sharing datasets and scripts is just a filesystem namespace operation. It's up to the system operators to keep the machine running well and influencing how it is used by i.e. setting up certain packages and services. It's incredibly productive to be in a tmux session with vim, mutt, tin, man pages, ssh, etc as your interface and minimal distraction.
