Yeah I missed the comments until I saw the archive. For some reason they aren't loading on the actual Mastadon page. I agree, its pretty unprofessional of them. Never been a fan of the "edgy corporation social media" fad and I hope it dies soon.
It seems like the server may be feeling the effects of the HN front page but it was already down with only two comments. There was a new breed of ActivityPub-amplified DDoS attack a week or two back on other Mastodon instances, so perhaps we're seeing more of the same.
