Furthermore, calling Camera Roll just a feature undermines its significance. This isn't just removing some insignificant feature like "search by focal length" or whatever. Camera Roll _was_ Flickr for many people. Not most of the total users, sure, but for everyone I know it was. For half a decade Flickr pushed it as _the_ way to use Flickr. It was what you saw first upon opening Flickr, and for any users to Flickr that joined in the last five years it was basically the entire interface.
Then it disappeared, supposedly for a very short time which then became very long... And then the updates stopped. During that entire time, myself and everyone I know that uses Flickr basically stopped using it. This includes people like me who pay for Pro. It became worthless.
The frustrating thing is that I really loved Flickr. I loved it so much I considered applying for a job there as the first job I've applied for in my life (I never apply for jobs, I just get referred to the company usually.) I loved it so much I evangalized it to my friends, family, random strangers.
But then the core Flickr interface, the way everyone I know managed and viewed their photos for half a decade, disappeared. And it's still not back. With the time, and the silence, I grew frustrated, and so did many people. I can't use it without Camera Roll, and everyone else I know can't either.
I really, really want Flickr to succeed. But this whole thing really stings hard.
