Forums, such as this one, are often held by individuals as an act of service to fellow Christians. They are not profitable or even self sustaining financially. Usually focused on particular groups.
They are built around a few personalities that are engaging and entertaining. Usually a few various "cliques" form of those who are here for socializing and those here to argue theology.
I've been members of several....been an admin and moderated many of them. The owners set the rules and regulations and moderators enforce them. Some are much better than others. Most forums have died because of the actions of the moderating team at the instruction of the owner. (Seen that more than once) And the people usually suffer because of that.
For this reason....larger social media platforms usually have larger memberships. Where the rules and enforcement are more even handed and consistent. Smaller platforms, like this one, form and have a few people who become friends. And everyone gets to watch...and if newcomers engraciate themselves in some fashion they too can become friends. (Blend of friendliness and consistently showing up)
I, and many others, have actually met other forum members in person and had a great time. I haven't met others from here...but on other forums I have(hosted parties and such) ....and am willing to do so again.
Online friends....success in internet friendships requires losing some anonymity. But it happens gradually over time. You get to choose to make friends or not.
