Who's leading the conversation?
This visualization below allows you to see the impact that each user
has on the current conversation.
The top row contains the group of users who have had the most impact, the 2nd
row the group of users who have had the 2nd most impact (et cetera).
Users with similar impact are grouped together, and the average score of the group
is shown to the left of the group. The author of the article is also shown on the
left, in their corresponding group.
Each user's score is based on the number of comments the user has made plus the
number of votes their comments have received. The scores are calculated relative
one another, so while their absolute value is not particularly important, their
relative difference does indicate a larger difference in impact on the conversation.
