I know it's possible to hide the number of 'likes' on each post, but might it be an idea to introduce an option for switching it off entirely? Call me cynical but it seems to me that many WordPress users click 'like' as a form of self promotion to get their name out but don't actually contribute in any meaningful way to posts. Of course this doesn't apply to all users and there are some who use the 'like' button as intended. However, I've recently had users scroll through and mechanically click 'like' on every post of mine without commenting once. To me, a 5 word one off comment is so much more meaningful than 20 'likes'. It's also frustrating as this practice clogs up the notifications area with meaningless stars.
Just an idea as I doubt I am the only one to feel this way about 'like'. I'm not saying get rid of the function but more to make it something that can be opted in or out of (completely).
