Everything has been bumped up about 30% This was to ensure 480p widescreen videos displayed. I had first tried 720p sized posts for retina display etc, but the reality is nobody has those yet. Full HD is the standard right now and that means content on my site should fit inside it. My site should be readable on a tv. It seems that about every 3 years its necessary to do a size makeover even if I've had the same monitor forever. Everything keeps growing.
