Thank you to all of you who commented on my message! As far as how many ..ODs are out there, I only follow APOD, EPOD, and ASOD, but a quick google search turns up a whole host of additional options. There's the Kodak Picture of the Day http://www.kodak.com/eknec/PageQuerier.jhtml?pq-path=2549&pq-locale=en_US&_r... Wikipedia picture of the day http://en.wikipedia.org/wiki/Wikipedia:Picture_of_the_day National Geographic claims to have the "Best" photo of the day http://photography.nationalgeographic.com/photography/best-of-photo-of-the-d... For another astronomy related option there's LPOD: the Lunar Picture of the Day http://lpod.wikispaces.com/September+30%2C+2013 Optics picture of the day, Geology picture of the day, Old picture of the day... ...and I imagine this could go on for quite some time. ~Kelly
