“Mouse over avatars to see who is paying attention to whom.
Yellow pays attention to grey; grey pays attention to blue.
Green is mutual.” 
For example (as of the date of this post):
- Paul Krugman pays attention to Freakonomics.
- It’s not mutual.
Scrolling is difficult, but let’s take that a bit further:
- Apparently Krugman pays attention to many, many people.
- They don’t pay attention to him.
Pondering: Is this a question of citing behavior more than one of attention?
