Most Tildes users (at least the ones who’ve been active for a while) don’t want it becoming like Reddit. It’s more a forum for thoughtful discussion than a link aggregator or meme/joke sharing platform. Low effort comments and jokes are literally marked as ‘noise’. It’s a quality over quantity thing. From the discussions I’ve seen there on this topic they’re quite happy to have “missed the boat”. This might change with time, but I don’t expect that to happen for a while.
