Black Backgrounds

Anyone whose website has a black background should be shot. Perhaps I should qualify my complaint: Anyone whose website is both content-rich and worth reading should be shot (figuratively speaking) if his background is black and/or there is anything in the reader's visual field that moves on its own. Content is king. Avoid clutter and newbie add-on crap. If you must advertise, do so unobtrusively.  Why drive readers away?
