The problem with Facebook and now Google+ is that these are not specifically designed for sharing photos.
Facebook gets more photos uploaded than Flickr can ever dream of, but they are family pictures or pictures of drunken teenagers, of poor quality in general. If you want to see art, Flickr is a wonderful place to discover amateurs with talent and there's nothing out there that can beat it.
Also, I think a photo-sharing service has to have good tools for exploring said pictures. On Flickr, even if it has many flaws, it is really cool to search for pictures with a high interestingness score and then to start following the people that took them. I found some breathtaking works of art that way.
On Facebook and G+ you have to rely on your friends-feed instead for discovery, but that's not how art is supposed to be discovered.
Flickr, for all its flaws, works for its intended purpose and can only be killed by another web service that is created explicitly for photo-sharing.
Google is in a position to do that however, but with Picasa Web and not Google+, although integration would be nice.
