This is an extension to my latest comment on this blog entry.
This exposes a flaw in the concept of Google search algorithms, as despite the quality of the content of the page, simply because it exists on wikipedia and is well linked within the framework of the site, it gets shuffled to the top of the google search page results.
Creating a page which is within the first page of the biggest search engine freely editable by anyone with any agenda is just asking for abuse.
Del.icio.us has been pretty free of spam and spammy links. The reason for this is their very logical decision not to allow search engines to index the pages by adding the following metatag.
<meta name="robots" content="noarchive,nofollow,noindex"/>
If wikipedia would do this it would solve a LOT of problems. The fact that wikipedia ranks so well not only means that objectionable content often floats to the top of the search engine rankings, but you also get a lot more random people who surf in through google (most likely looking for information) and end up editing the article and bringing the quality down.
So this is a callout to wikipedia, please get your pages out of google and work towards refining your content rather than being a nesting ground for link spammers, people with personal agendas and random vandals.
