Having used your new system a bit, there are some pluses and minuses.  One plus is that when you see the reactions, you can look at who's posting the reactions and get a sense of which group of partisans is reacting.  The reaction options (like/funny/wow/sad/disagree) add three more options compared to the like/dislike we had before.  Not sure how to interpret "wow".  Is that "Wow, that's brilliant"? or "Wow, how ill-informed"?  

In the past, clicking on the poster's alias allowed us to see their profile and posts.  Will this feature be reinstated?  In judging a person's contribution, it helps knowing what they wrote in the past, and which positions they took.

If one is participating in a dialogue with other posters, is there a mechanism to quickly go to the posts one has written to see the reactions?

If a certain poster appears to be a troll, is there a block or disable feature that will block their posts from your view?  Is there a way to determine is the poster is a bot?
