Looks like Danny Sullivan headed over to Wikpedia and added some links including one to his site on their page discussing SEO which only had links to search engines. This did not sit well with a wikipedia editor which removed the links and sent Danny their form letter saying "Please do not add commercial links". Danny responded with a well-written email that points out some issues with Wikipedia including the fact that search engines are commerical sites. Luckily they posted his email message. I hope you have as good a laugh as I did. IMHO this is as funny as the Adsense rep calling John Battelle.
