In case you aren't aware of it, a vote is taking place at http://en.wikipedia.org/wiki/Wikipedia:Nofollow regarding the use of "rel=nofollow" in the XHTML generated for external links on the English Wikipedia. This attribute causes Google to ignore the link when it crawls a website. Kate stated in #mediawiki that the developers would respect the results (either for or against attribute use) of a project poll, so vote on the matter if you are so inclined. Remember that the results of this poll will only affect the English Wikipedia.
