On the Twitter front, the winner has to be the person (one of us) who has the famous person following us who in turn has the most followers divided by the number of people they follow.
I have someone following me who has 3,047,684 followers and is following 327 people including moi.
That gives me a Twitter Famous Follower Boast factor of 9320. OK. Everyone else: GO!
This is going to be brilliant... My score is going to be so low!
If you take "brands" into account, Superdry follows me:
42,887 followers vs 1,111 following = 38.6
So far the best "human" account I can find for score is a guy I know from b3ta (he was the guy behind Sickipedia),
cr31,322 followers vs 230 following = 5.74
Edit: Team_Moyles follows me, which ironically gives me a much better score:
14,011 followers vs 70 following = 200.15!
