Anyone who has run a donation based service will tell you whatever % of users you think contributes back divide that by 1,000 or 10,000 to get the actual number.
The elephant in the room here is how you ethically get people to onboard without an existing community / fomo / money.
The trick is getting the content creators there, but most of them are ultimately and fairly interested in making money, and your new platform wont have that for them.
Bluesky has done alright, but that was a black swan event Elon Musk inspired.
It doesn't have to though, we could train AIs that push back or even coordinate with a human therapist similar to how self checkout lines still have an attendant.
Yeah, exactly, it isn't reasoning or creating in the way that humans reason, it's calculating that statistically speaking, when a human says what you said here's roughly what often comes next.
It's like debating your political other. You can often predict what they will say not because you understand their reasoning, but simply because you've seen multiple times how they react to a given argument in the past.
It's a silly but spooky thought that this or similar interactions may have been the butterfly effect that drove at least one of them to take their company in a drastically different direction.
There's also quite a difference between the ethics of healthcare and legal services.
Most of the time if you need a legal answer from a lawyer who charges like that, it's because you know you'll net more money from having the answer than it will cost to get a reply.
With healthcare, you're not trying to make money you're just trying to live.
Yeah one key missing feature is subreddit creation and moderation.
Without all the free labor from moderators curating content for topics with different tastes and ideas about what the community should be, it's going to be a struggle to build a community.
Even if you go on like Reddit if you post certain things in certain subs you'll get invited to private subs talking about whatever niche topic.
Same with Discord, lot of small communities there.
