that the percentage of nofollowed links on the entire web is only a single-digit percentage, and "in fact it's a pretty small single-digit percentage".
I find this hard to believe. Just look at all the big websites that automatically add nofollow tags to all external links:
-- Wikipedia and most other wikis
-- facebook and most similar sites (I'm not sure about Google+)
-- Ehow and most other content farm sites
-- Most forums
-- Most article sites
Cutts' statement might have been true 5 years ago, but I strongly doubt that it still is.
