Nathan Weinberg linked to a post by Emad Fanous who notes that the W3C is selling PageRank 9 and PR7 links. You can buy a link on this page also and earn yourself a PR9 link from the w3.org site. How much is it? $1,000 per year and if you do that, you will also get yourself a free PR7 link on this page. How about that for a good deal? :) I'll stop being sarcastic now...
Things to note:
(1) The links do not carry the nofollow attribute
(2) It seems like anyone can buy the links. See the links listed, "Website Templates Company," "KVM Switches Online," "Cheap Web Hosting Provider," oh and a familiar face, "SEO Book," to name a few.
Is there a difference between having links to "supporters" and selling links to anyone? This is not for me to decide.
