Two serious, non-cheeky questions:

--does Android's Camera app have social sharing features?

--does it provide some kind of cloud-based sharing support?

I see the above, plus Instagram's 30M+ user base, as their main benefits.

Because of Android's intent system you can share it over literally any social vector installed on the phone.

Here's a screen shot of the sharing options shared via Dropbox.

It's a little faded because the screen shot button combo includes the back button on my phone... not the greatest design.
