Two more thoughts:
- If millions of nofollow links from Wikipedia, TripAdvisor, and other megasites or corporate sites aren't affecting the link graph, then why does Google worry so much about paid links (which presumably would be easy to detect and neutralize if used on a scale that was big enough to influence the link graph)?
- It seems to me that Google made a mistake when it told site owners to use "nofollow" for ads and paid links. It might have been better to create a new tag (say, "ad" or "paid") to distinguish such links from nofollowed blog links, Wikipedia links, etc. that might have value to a search engine. (Google might not want to follow a "nofollow" link, but I can imagine a scenario where Google could find a relevant nofollow link from Wikipedia, TripAdvisor, etc. useful as a citation even if the link didn't pass PageRank.)
