Nofollow Not Meant For Every External Link

NoFollow Nastiness – a Big Boo
for Google!
is a nice look at Threadwatch on how some people are making use
of the nofollow
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.
