Unfortunately there's really no equivalent pool of photographic content--including CC and public domain content. If flickr were to shutdown, a huge amount of content would be lost.
I sort of agree with you but in another sense it remained true to its roots as a photo publishing platform, mostly, for amateurs. But the mass market was fine with putting some pics up on facebook. And serious professionals have other markets more explicitly aligned with their needs.
Perhaps this could be a clarion call for volunteers to start transitioning the CC and public domain content to archive.org, assuming Flickr gives enough notice that such a shutdown were to occur.
