Of the top 20 weblogs on the fan-favourites page, I read only 4 of them, not including my own site (thanks, by the way), and read one other occasionally.
I read 5 of the next 20. None of the third 20. 2 of the 4th 20. And 1 of the final 20.
12 of 100. There's 33 weblogs on my favourites list, 9 of which I haven't visited in quite a while (their links weren't purple in my browser). Therefore, half of the sites I read aren't in the top 100.
