The fine folks at Flickr have released a new product: Organizr. The key bits are better browsing (time and tag based), photo collections (including custom presentations of photo groups) and users can define their own groups for social photo management.
Oh, and they plug their API right off the bat and taunt folks into doing something better. This in fact may be the biggest part of the announcement.
It's sort of neat to see the folks at Flickr reposition the company and still innovate. Remember when they first started, it was all about using photos to initiate chat. Now it's more about plain old photo management, integration with other Web publishing tools, and social translucence.
