a few flickr tools…
fd’s flickr toys – scout is handy if you want to find out if you have been deemed worthy of flickr’s interestingness rating. my umbrella made it to no 1 in interestingness for the day it was uploaded but has now slipped back down to 227!
flickr leech is a good way of scanning lots of images from a group or tag
anoptique flickr mixr is handy if you want to pull out the latest photo with a particular tag (such as gracelondon say)
