For topics that come up over and over and over again on Hacker news, I have a 251KB flat text file with some references on various topics (and a few of those appeared in my reply to you). The particular TED talk was memorable to me because a local researcher shared it to an email list for the journal club I participate in, and then I posted that TED talk to my Facebook wall.
