I wanted to share some observations because I think this topic speaks to a greater paradigm shift in forum ownership and management:
Hosting Administration - This topic, as a whole, is tapering off. There's not much future in trying to engage in conversations around hosting administration. Why? The world has moved on. There are social platforms where starting a new online group is as easy and seamless as one click; there are cloud services - including XenForo - where launching a new forum is as easy as one click. Hosting Xenforo is relatively the same ten years ago as it is today. Independent hosting used to be a necessity, but the reality is that most modern users don't really want or care about the back-end when there are better, more frictionless experiences of everything from Facebook groups, Amino Apps, MeWe, Discord, and more.
Community Management - This is still ripe for conversations, and I think we're still not even scratching the depth of human behavior. This draws upon disciplines such as organizational management, human psychology, group behaviors and more. How do we engage, motivate, excite, and influence both individuals or groups? This is something that is uniquely human.
