As an Android user, I use the mobile web version with Chrome. I appreciate the fact that the mobile site now supports the "appreciate" button, but it's very hard for me to tell if the appreciates are from me or some somebody else. I think there's a nearly imperceptible difference between the look of buttons for these two cases. This often leads me to un-appreciate and then re-appreciate.
I'd appreciate it if my apprentices were easier to spot.
