Kind of undecided at the moment, but I definitely don't support adding names. Not only do I feel that would create unnecessary clutter, but given the way I've seen people treat others who present an unpopular opinion, showing those who agree with the post could only make that worse.One benefit I can see to a system like this would be that it would provide a contemporary alternative to "I agree" posts. I don't know if those are as much of a problem now as they were a few years ago, but it would still allow people to support an idea without feeling pressured to provide additional discussion.
