I have a (VERY) carefully-considered suggestion to make.
I know a lot of photographers have been calling for a total ban on the "dislike" option, but I would actually say no, let the "dislike" option continue.
However, anyone who "dislikes" an image should a) be identified and b) give a reason for the dislike.
Personally, I would never retaliate against anyone who "dislikes" my work. That is their undeniable right in an international artistic democracy.
I believe in the full gamut of artistic criticism - without the cloak of anonymity.
Anonymity, alas, spawns cowardice, which has no place in this global village.
