I think both private non-anonymous reactions and public anonymous reactions are likely to be valuable, whereas public non-anonymous reactions could be potentially harmful and private anonymous reactions seem mostly useless.
“I’ve seen this” coming from the parent poster and “nice post” are valuable feedback for the author of the post/comment, but less useful information for other people so it would best be private and non-anonymous.
Reactions that say something about the content of a comment, like “interesting” or “confusing” are more useful if they are public and anonymous.
