It would be odd if, after viewing/reading the exact same content, we all had unique opinions of what we just saw or read. It would be pretty bizarre, and probably imply that our communication system wasn't working. It's good to see more than one POV, but that doesn't mean we shouldn't ever have agreement either, and if I see someone has already made the same point, why should I type it in?
Admission: I didn't read absolutely every comment here before typing this; just the top dozen or so. :)
