It seems that we can't see who likes our posts/comments (or I haven't figured it out). Is that intentional and can it be changed? I'm not sure I need to know who likes what's said, I was just surprised it wasn't visible.
Great question, @Luke Shiras!
Reactions (Likes) are anonymous. We are currently not making Reactions visible at this time. We also have the platform preventing reaction pop-up notifications as well in order to reduce the amount of spam or unwanted/needed notifications.
