Do you want to quickly see the "best" pictures someone has on Flickr (even when they have thousands of pictures)? This tool allows you to quickly and gracefully see the most "interesting" pictures a user has on his stream through his/her buddy icon menu. It also adds a "Pool Interestingness" link to the main page of any group.
As always from Mortimer, this script is very useful and has a very nice and neat code. A must for any serious Flickr user, IMHO.
