Okay, so this new iOS app from the Tumblr peeps is awesome. (No, you don’t need a Tumblr account to use it. It’s a stand alone app and service.)

Using your iPhone or iPad you snap pics or add them from your camera roll, arrange them around in a grid, and then upload the photo set to a private URL and share with whomever you like.

My quibbles so far: (1) you can’t select multiple images at a time from the Camera roll (you have to go back in and drill down several taps for each and every image you add); (b) you can’t edit, update, or even delete a photo set once it’s been published.

(Also, anyone else thinking Flickr should have made this app?)
