The about section has a philosophy section which likely took longer to write than was taken designing the website, and one of the top posts is about how they're going reorganise everything into their equivalent of subreddits. What's the point if you only have 100 users?
Reddit thinks they don't need mods. Tildes seems to think they don't need users.
it's intended as a spiritual successor to pre-diggpocalypse reddit.
Because the guy who created it, seemingly doesn't get that times have changed. I mean, the nokia 3310 was a great phone in its day, but it's 2023.
And I get that they don't care, but if your main audience is former mods who like organising things without the interference of users, they're not going to have enough or sufficiently interesting content to attract critical mass and a wider audience.
At which point, you might as well turn your reddit replacement into a wordpress blog and have the same discussions you're having now in the comment section. Because unlike tildes, people are working on plugins which will allow wordpress to become fully part of the fediverse.
