This is great news for people like me that continue to use Flickr after a very long time... Unfortunately the new UI reminds me a lot 500px which I think offers, at the moment, a much better community and user experience if one is really a photography enthusiast.
Anyhow hats off to Yahoo for trying to make things right after several years of stagnation. I'm aware the Flickr team have lost some valuable members and that probably affected future plans but that's a different story.
