This is a great tool! Measuring your Tweet load in Scoble units is brilliant. I'm unfollowing my top 4. I can't bear to unfollow #5, @gapingvoid at 150 tweets/week. After that, the next 4 are going, and #10 @mike_ftw gets to stay with his 82 tweets. Not bad at all, I feel like this is really going to help me focus on the neglected long tail of people I follow who don't tweet 20+ times a day.
