i saw a discussion on cohost a while back in which folks w/ eating disorders were talking about how content warnings on websites for posts involving food actually exacerbate their issues because it frames "food" as something that needs "a warning" and i'm interested in seeing perspectives on here about this.

We have an expression around here: One has been "Alton Browned" when one has been exposed to some media presentation or conversation about a particular food item, and within a week that food item is created or purchased and consumed.

It's a susceptibility to suggestion that leads to eating.

More broadly, I think I would like to see obligate metadata on all posts. It could be done automatically by word frequencies or vocabulary, or even as a by-product high level semantic compression.
