NoFollow Nastiness - a Big Boo for Google! is a nice look at Threadwatch on how some people are making use of the nofollow attribute as a way to prevent link love from going to resources that many might say deserve it. For example, documentation from Apple on the Canvas HTML element gets a nofollow from the Mozilla Developer Center referencing it. It's an ironic twist. Nofollow, now just over a year old, was introduced in part to help search engines prop up the value of link analysis. But if it starts getting used as an attribute applied to any external link, that will just make link analysis even more devalued.
