I still need to determine whether it's worth reading. Private diaries/libraries are still useful, both for the writing and for the lack of publication.
That's why there should be a way for people to voluntarily designate that what they are writing is not worth reading!
I know sometimes I want to respond to something, but know that my response does not contribute anything useful, and so I wish I could respond in a way that would only be shown if someone opted in to seeing messages self-described as useless.
