I’m a fan of serif fonts, so I’m a little sad about that change, and a little confused why posts and comments are in a different visual style. I’m definitely no expert on stuff like this, but I’m curious if there’s a motivation for that difference.
edit: oh, and it’s even different between section headings and post paragraphs, that seems weird to me too, but maybe it’s more common than I realized
While I agree it would have been significantly better to send this to the org ahead of time, I think on the margin I really wish we had more random spot-checks and discussions of org decisions, and still prefer seeing a post that puts an accidentally heavy burden on the org than not seeing one at all.
