Photo Session From Flickr, Browse Photos With Your Friends

"Flickr has introduced Photo Session, a new feature that lets a group of people browse photos together from multiple devices - both mobile and desktop."

This seems pretty slick, being able to have up to 10 people viewing and chatting about your photos in real time, and even works while you are uploading photos to the set. This will work on iPhone, iPad and the desktop, so pretty much anywhere you are you can use it. Yahoo! should do more stuff like this with Flickr, they may have their niche!
