Being in the printing field I like to keep up with how people are displaying their images. Once you have taken and processed your shots what do you do with them? Display on screen? Ipad? Print at home? Print through a lab? When printing do you print at the 4:3 aspect ratio or crop to "standard" sizes? Personally I love the 4:3 aspect so I print 4.5x6" proofs and display enlargements as 6x8", 9x12", 12x16" and 18x24". For some reason I am not a huge fan of 15x20" prints, not sure why, just a preference.
