Social media, gift that it is, has fundamentally broken two concepts I think. The “friend” and the “like” now no longer mean what they used to, and culturally I am not sure we are not really ready for that change:
“Like” has come to mean that you have seen something, agree with it, do not agree with it, enjoyed reading it, disliked the writer, want to suck up to the writer, trolling, wanting reciprocal attention … whatever.
A relatively simple fold, nice application of colour change and some critical shaping. make this icon relatively recognisable.
