As a parent, I think this is a great idea. I have trouble sharing photos with family members, not all who are on Facebook (my default sharing method). Plus Facebook's privacy settings are confusing, and their business model runs against keeping my photos private, which is somewhat unsettling.

FYI, Ash Maurya built CloudFire to solve this problem, but since he's moved on to being a "lean startup" guy, the product seems to have been abandoned. There are probably valuable lessons in the history of that product.

Finally, I have to admit I'm getting tired of the landing page gambit. Maybe it's just early-adopter-itis, but if I'm interested in your product, I want to touch it, play with it, right now.

A landing page doesn't solve my problem. And there are so many "landing page" products in existence now, that I question whether the strategy is beginning to turn people off.

Having to wait for a product that on average never actually ships is annoying. Don't bother me until you have something to show. YMMV. :)
