There are two famous Seths in the blogshere: Seth Godin and Seth Goldstein. Seth Godin is a marketing guru, writes a very popular blog and also owns Squidoo.com. Seth Goldstein is working on “attention” and also has a blog. I have been tracking “attention economy” using squidoo: see this lense. But I’m not sure I understand Attention Gang’s work at this point. Also I’m not sure if two Seths know each other.
