Sorry, spidermike, but I have no trouble with someone posting a quote like this with or without their own take on it. It is thought-provoking and helps in the understanding of photography. One can chose to contribute to that discussion or not. It is certainly atypical of forum posts, but I don't see it as being out of line.
The quote certainly causes me to think and rethink my take on photography as art. I don't think it changes my mind, but it is food for thought.
If it was a quote like "the sky is blue", then I would agree with you regarding the usefulness of it.
