We're not sure if this an officially endorsed TheChive app or not, but it's nice enough to pass along. TheChive is a pretty popular photo-entertainment/humor site (link) that has also pulled off some funny pranks/memes in the past.
Basically, it's a great time waster and the app by Full Revolution, Inc. is pretty minimalist but slick. As a result, the app is too the point and zippy for what it does: deliver the latest, greatest photos to your phone. It has all the major categories and even allows you to save the pics. There's no direct sharing option though nor search but ads are barely there (they show up only if you click a photo).
So if you like TheChive and/or like looking at interesting pics, here you go. Pick it up for free in the Marketplace here.
