Derek Powazek —  whose wife just happens to be flickr's community manager — is reporting that he recently received two interesting pieces of mail from flickr. One was a giant print made from a random assortment of Powazek's flickr pics. The other was an 8x10 flickr photo book. Of course, similar printed products have been available from other services for some time, but given flickr's success and the passion of its members, this could be a huge hit. Can't wait to see this go public!
