User blog comment:LaughingJacks/My Review Of The "Nice Work" Addon/@comment-26437440-20160830201804

I still prefer to leave a message if someone is making exceptional edits. Easier to let them know exactly why their work is good, rather than a generic "nice!" button. Same for a bad edit button. It could potentially have some use, but I could also see it being abused and again it doesn't let a user know why their edit wasn't good.

I don't think it should be removed, but it could definitely see some improving (likely since it's new) and at least be made optional.
