That right there is why I won't go anywhere near your site. Sorry, but why would I invest my time and energy, and photos, and inviting friends etc if you've got no visible means of supporting yourself? There's a reason I pay good money to Smugmug.

That aside, I have no idea why I would want all my photos on the one site. Is this the "one ring to rule them all"? Do you expect me to point friends, family, clients etc to your site? Is there realtime sync'ing from my computer? I don't understand who this is aimed at and what pain you're solving.

I also find the name a little odd (Gush?!) and the url particularly so. "Gush", in the traditional sense, suggests flow, water, emotional outpouring (ok, good) but you might want to watch out for the colloquial definition: http://www.urbandictionary.com/define.php?term=gush The name also says nothing about photography, nothing about the app and the "get" is awkward (yes, I know other startups have used it but that only makes sense if I'm visiting the site to sign-up. Could you direct your grandmother to "Get Gush"?)

Sorry to be cruel -- I'm not being deliberately mean but you asked for criticism.
