<p>From my point of view the main reason I dislike cross posting is the potential waste of my time and that of other users answering some question which has already been answered elsewhere. Given that the comments which the OP has posted specifying the cross posts are very helpful as I would not answer any question where I saw such comments. It seems less necessary to also close the question as if someone wishes to proceed to answer it in the knowledge that there may be duplication of effort then that is their privilege.</p>
