My inspiration for PicDigest: the hassle of getting my mom and dad and grand mom (et al) on Instagram and showing them how it works...just so they can see all the pics I post of my new son.
This would also be cool with Dropbox. I know people have shared albums with new pics added every-so-often.
And a printed option (someday) would be nice too. Something like the recipient can one-click to get a printed version sent to their house (and I pay).
But very cool anyway.
And photo printing for your recipients will be added before the oh-so-important photo printing holidays (Christmas and Hanukah).
Thanks for the ideas!
