I was having an email conversation with a bunch of guys back in Chicago today, since I am going back there this weekend. As I was in GMail reading one of the replies, I noticed these sponsored links right next to the thread:



The thread had absolutely nothing to do with farting (nobody had even mentioned the word as far as I can tell)! Anyway, we all got a good laugh out of it. Several of the other guys on the thread were seeing the same links next to the thread in their GMail accounts, so it wasn't isolated to me. I really wonder what part of the algorithm tied our conversation to those links...
