On the forums which there are on the internet, the convention among those who useth them to converse among themselves be such that one proposeth a topic about which to hold a conversation, and the others who have any interest in said topic follow with comments and questions in a thing they call a thread. That is to say, they generally believe there should be a connection in content betwixt the initial post and the comments which follow, and such connection will be assumed even when it is not made explicit by the author of a comment. Thusly I assumed thy comment to be in reference to the words of the starter of this thread, who appears to also be the author of the piece to which he shared a link. He thus is, in my estimate, the author of a photography publication. Therefore, even when you say you didn't mean him specifically (which is, as I tried to explain above, not an easy thing to understand without additional explanation as it would appear to be against the conventions of a forum and conversation in general), he is one of the many who you say your comment refers to.
Of course it could also be the case that I missed a meaning of the word you used, and went too far in assuming that in fact it referred to the author and not the publication, the latter being what you wrote. If you meant that the publication cannot read and/or write, I'm sorry for my misguided attempt at reprimanding what I felt to be less than polite words.
