The iPhone, iPad and browser apps connect with Facebook and sort you and your friends' photos into categories like "most popular" or "family updates." It also makes piles of the most popular Flickr and Instagram photos.
With the new category, users also get a log of what was most interesting to them in real time on Facebook. Since I'm personally a fairly conservative liker on Facebook, the collection of photos in the pile turned out to be something of a highlight reel.
Pixable is one of the only photo startups that is focusing on aggregating and browsing online photos rather creating a photo service of its own -- a smart strategy in a crowded startup space that big players like Twitter have recently entered.
