Image posts do not exist and we usually prefer medium to long text and videos that are dense with content. It’s not entirely formal though, and there are avenues for conversation and personal expression. The announcing post: https://blog.tildes.net/announcing-tildes
Extended docs and the philosophy of Tildes: https://docs.tildes.net/philosophy
Tildes' content is open for anyone to see: https://tildes.net/
We have a subreddit: /r/tildes with a permanent thread for invites and there are invites for everyone.
If someone made a civil argument with citations, leading to a conclusion you find immoral, but you didn't have the expertise to find errors, would you delete it or leave it up?
Tildes is definitely not a place for free speech absolutists.
The Tildes founders looked at Reddit, then what happened to Voat and identified the problem as a social one, not a technical one. The problem with Reddit and Voat lies between the keyboard and the chair. This is why they focus on the quality and good faith of the discourse, instead of metrics like growth or mass appeal. They aren't aiming to be a clearing house for all means of social interaction in the way that commercial social media platforms like Twitter, Facebook, and Reddit are.
For what it’s worth, Tildes is more free than it seems at a first glance. But we’re determined to not be another victim of the paradox of tolerance.
I think content moderation could be done by the community flagging problematic content. Flagged content could be temporarily hidden, with the reason it was flagged. The OP could then write a short defense of the content, and then a "jury" of randomly selected users (who are over 18) could vote on whether to permanently remove the content or to allow it. Content couldn't be flagged again for the same reason if the jury had previously approved it. There would be a public record of content removal decisions, and perhaps even a restricted way to somehow request the removed content as a matter of public record, without surfacing it into public view.
Obviously, there would need to be some experimentation to get a better system. Which is my whole point. I wish there were more systems experimenting with this.
