On the surface I love this idea. Flickr has been stagnant for years and starting to worry me. I don't mind paying for a photo sharing service but the market sure is saturated. I'll be looking for a little more than a pretty, overpriced UI over Amazon's S3.

Wouldn't it be great if a company came around and offered front ends for S3. One for photo sharing, one for docs. You could switch them out like skins. Your data is in one place and never moves. If a competitor comes along with a better front-end, you could change to them.

That would also be nice, because then you could have one monthly fee for all of you online storage needs. Let's be honest, they're all hosted by Amazon anyway.
