These changes really speak for themselves and if you've ever tried Instagram, you're basically getting the better quality photos: clear, crisp, tons of space, and very balanced filters. I love my iPhone and these guys deliver awesome app without being overpowering. As some of the other comments noted, "above and beyond" Instagram.

The new design is great: modern and a little bit more flat for a modern look. I was actually kinda bummed because like....they got rid of the Pro badges....oh well. My photo gallery stands out and looks pretty sharp. Well done, Flickr.

Anyway to sum it up, these changes are nice. And with a free 'old Pro' features, they're definitely a no brainer. I think any photographer can enjoy these changes as much as any casual photo sharer. Yahoo does it again!
