Can Flickr be saved by Marissa Mayer and the newly invigorated Yahoo? I'm certainly happy to see how my photostream looks now with the much needed UI update. The Flickr iOS app is finally excellent. If only Flickr had done this app sooner, we'd have probably had no Instagram. However, it might all be too little too late as almost all great photography has already moved to 500px where photos are still incredible and the UI design is still a lot better. 

This photo is from Week #131/300. A hot, sunny day last year. We haven't had any hot or sunny days this summer yet.
