I don't think it's worth talking on a blog post or in a technical forum just for social reasons (e.g. I don't think reddit's meme or pun threads would be valuable on hn for their social effect), but I agree with you because I don't think a comment has to add to The Sum Total of Human Knowledge™ for it to be valuable. It just needs to be an interesting thought that the readers aren't likely to have had on their own.
