The range of "reactions" also promotes divisiveness.  It is rather easy to ignore a trite, offensive or disagreable comment from the "regulars". Ignoring sort of dampens its impact; like not acknowledging an interrupter. Just having the "like" or nothing seemed less antagonistic. I do like the "funny" though it acknowledge humour as a "good", but even that can be sarcastic - I know, I was tempted.
