Flickr adds clusters!

http://www.flickr.com/photos/tags/make/clusters/

“First up is clustering, a better way to explore photos through tags. You can still see the most recent photos with a given tag (say, summer) but now you can also root around the finer distinctions: summer beach vacations versus summer flowers and nature – and all the clusters are collected on one page. It’s neat!”

Man thats some cool stuff. The first link is for “make” which is a DIY magazine im a huge supporter of.
