I’ve gotten a lot of negative feedback about this recently from people who want to see when they, themselves get a best answer, but not when someone else does, so they can’t just turn it off.
Also, I have reports that people who are watching the first post only are getting notifications even though that isn’t a first post, and also even if they just read the post and are not watching it.
Some of them may be overlooking a certain setting… not saying all of the self-reporting is necessarily accurate… but it does seem like there should be a way to go back to the old way where they only got notified for their own best answers.
Not everything you read is in pursuit of an answer, especially on our site. They are looking to see if they can help, and so unless it is about their own answer, it is arguably unproductive/unhelpful to get those notifications.
