This is a special post for quick takes by Neil. Only they can create top-level comments. Comments here also appear on the Quick Takes page and All Posts page.
A functionality I'd like to see on LessWrong: the ability to give quick feedback for a post in the same way you can react to comments (click for image). When you strong-upvote or strong-downvote a post, a little popup menu appears offering you some basic feedback options. The feedback is private and can only be seen by the author.
I've often found myself drowning in downvotes or upvotes without knowing why. Karma is a one-dimensional measure, and writing public comments is a trivial inconvience: this is an attempt at middle ground, and I expect it to make post reception clearer.
