It needs an overhaul, but it does what I need, which is share a few hundred images, broken up into sets. I've tried a couple other sites and apps, and haven't switched yet.
It does what everybody needs at this point but people have drifted towards services like Instagram because it is so well thought out and easy to use.
In a lot of ways most people are looking for what Flickr offers but refuse to use it. They want privacy, a place to back up their full-resolution smartphone photos and for a very cheap price.
Depending how much you trust Google's privacy settings, doesn't Google+ fit that bill? I don't think it's what photographers really want, but it sounds like a solid alternative.
