I've found that nobody here likes Hiki, and most haven't tried it much, if at all, even that dislike it. It's probably largely assumed what it is, but I can tell you what it is now from experience: It's autistic people being able to say even less and having to be even more polite than social media in general, and then, having to pay for attention. It doesn't have to be that, but you aren't allowed to express your legitimate anger with any group or member they protect.
