As I understand it, it's not a technical problem, rather a social one first off: you can build it but it'll be "empty" compared to all other options out there, even if it's technically superior to them. Network effect and all that.

There's also a technical problem you'll have to contend with: bots and scammers... so many bots and so many scammers.

Totally. It's a very boring part of this that one would have to contend with.

I kinda feel the same way about Facebook. Groups, events, marketplace are amazing for community building. But it's just so hard to compete with Meta.

I think it's an interesting area, but I've got no time or energy to undertake such an endeavor. However, I'd be happy to talk about it and discuss it further if you'd like to. Contact info is on my profile page here.
