A WebmasterWorld thread points to a DuckDuckGo, a search engine that competes with Google, help document that says that to rank well in all search engines can be done by getting good links from sites like Wikipedia.

I guess no one told DuckDuckGo that links on Wikipedia are nofollowed and Google and Bing do not count those links.

The help document says:

There are some SEOs that feel even nofollowed links on Wikipedia play a role in Google’s rankings. But Google has said numerous times, any nofollowed link, on any site, does not get counted.
