>In 10 years, you can completely replace larger platforms as the community of choice.
And by then you have to worry about money to upkeep the platform. You sell off or sell out your users, and the cycle repeats. Even for the most well meaning people, it comes down to the fact that scaling such communication isn't free.
We hear all these stories of eccentric billionaires going all out on their hobbies. Why do we have no eccentric FOSS people who donate to keep such stuff FOSS?
> scaling such communication isn't free.
So don't scale. There is a sweet spot where a few $2 classifieds (e.g, for motor vehicles) will sustain your operating costs, and the high-trust environment keeps moderation efforts/costs low, while the total target audience is too small for most bad actors to bother with.
Sorry, but to host a small community on a v-server costs you today 3,50€ - 15€/month, when you can't pay that, you have other problems than the dying internet. It's not 1990 anymore...
What if they're not scaled? What if scale is inherently constrained?
Going back a bit further yet, I also miss local BBSs. Some were popular while many others were not. Almost all of them regardless of popularity were a labor of love: Very few BBS sysops ever recovered what was spent to start the thing up and keep it going and it was not, broadly speaking, an inexpensive hobby. It was a mosey-losing operation.
But since long-distance telephone calls were billed by the minute, the systems were geographically-bound by the financial disincentives of far-away users. This made for tight, local communities (often with small dozens of semi-active users, and sometimes even hundreds!) and pretty effectively kept the idea of global domination-style growth off of the table.
So, again: The constraints shaped it to be how it was.
What kinds of constraints might form a path towards to this kind of small success today, in 2026, while there are giants like Meta stomping around?
