I tend do take pics of what I want to take pics of, and I do it for me. If a million people have taken the same scene, good for them! They haven't taken the one I have! If other people like my pics, then its a bonus, but that makes me happy!
I had a mate at work (who is a bit of a Flikrer) have complaints made against his work because they were taken from the same locations as someone else, whos work he'd never seen. Different images, vaguely similar look and feel, but then there were limited viewpoints of the Severn Bridge from below and taking a picture of this subject at sunset was always going to lead to similar images! To my mind, complaining is just churlish! You can't copyright a view! (as much as some may try or some may wish.... whatever happened to that case of someone trying to copyright the image of Parliament with a london bus from Westminster bridge I read about a few years back?) You can't completely replicate someone elses image, and to my mind, trying is flattery.
