It seems that photo applications, be it mobile or web, are making their presence felt via small but innovative ways in which they bring photographs together. Facebook is the largest photo sharing site available today and if you can somehow tap into that to create an interesting social experience, the results are bound to be dramatic, as Pixable’s Photofeed application has managed to do.
You've spent years sharing your life on Facebook, Twitter, Foursquare, and recently adding photos to the mix with Instagram. If you're like me and many others, sharing this stuff also serves as a means of archiving things to be able to easily look back later and say, "remember that? That was great."
