I don't like this new system at all.  Based on the comments I have read on various articles, they are not more 'civil' at all.  What I find is that many voices are missing - from multiple points of view, and not that they were necessarily 'uncivil' before.  We seem to have some diehards who continue to comment, and frankly it's a less interesting conversation.  Also very hard to read (bad font and colour), and the choices for reaction vs just a plain up or downvote are not adding, but detracting from intelligent discourse.
