"Only Shutterfly Collections offers your own personal page for sharing. Create up to two Collections, each with an address that you choose, like TheMartinsPhotos.shutterfly.com. Your Collection gives you a “meeting spot” to gather pictures for everyone to enjoy."
On the surface, this service appears to work a lot like Flickr. Photo sharing and blogging seems to be the latest crazy these days. Everybody wants a piece of this market.
