Last week Flickr launched their long awaited feature Collections, which is sets of photo sets. It’s been one of their most requested features for the last couple years.
To see it in action, check out my SXSW Interactive 2007 Collection.
What are collections, you ask? A collection is a container into which you can place either sets or other collections, allowing you to create a hierarchy as deep as 5 collections. You can place as many of your sets into a collection as you like, and a set can be in as many different collections as you like.
They also added the ability to change the layout of your Flickr photos page.
