Often I see a post which I appreciate and want to show my support for, but I do not feel I have anything meaningful to add to the conversation, so I just let it slide rather than cluttering up a
thread with lots of "Yeah! What THEY said!"
I thought it might
be nice to have an option to click a "cheer" button at the bottom of a post, just to show general support, agreement, or applause, so people would know their contribution had been read and appreciated whether or not any real dialogue was happening.
