Having decided I should try to make a first appearance on Friday, even while battling to clear desks ready to head for the coast, a few hours after seeing this notice, another channel led me to: http://lesswrong.com/r/discussion/lw/8ts/open_problems_related_to_the_singularity_draft_1/ which is of clear interest to a few locals.
I promised some follow up on Orca (Killer Whale) intelligence.
I'd suggest starting with a couple of extensive documents, one historic and close to home and the other contemporary and global. Neither talk directly about "Intelligence" which only makes their evidence more persuasive to anyone who accepts the uncomfortable fact that h.s.s. is not the purpose of evolution.
