Last night a PR manager from the New Yorker emailed me about the Terry Semel interview, so I watched it and put up a link to the actual video. I emailed a few SEO related bloggers about it and thought nothing more. (other than the interview being great insight into Yahoo).
While I’ve had other things hit Digg and grow traffic as part of a SEO program, this was 100% natural. There was no suggested email to a large network of friends with digg accounts or anything like that. Not that I would ever do THAT.
