Yahoo using NoFollow in Organics
This was a odd one that I saw first thing, I had been running some of those secret tests that even the boys in the office don’t know about lol 
they where to do with one box triggering ( btw Google won on the news one box early today again, but if Live had the traffic the triggers would occur at the same time I guess ) anyway I searched Yahoo for good times and got this :
The pink bits are Nofollowed links, not sure why Yahoo would do that unless they where allowing the spiders into the results

http://www.e-business.ieBecause those are anchors on the page and so just the one link for bots to follow to the one page? Seems to be just for Wikipedia, maybe they made an agreement to give those sub-links for more control over the spiders paths for statistics or link juice reasons. (Or am I completely off the mark?)

http://www.mysqltalk.comHi Dave,
That’s very likely a Search Monkey result:

We have a meetup tomorrow with Peter Mika:

I’ll ask him if that’s the case.

http://www.mysqltalk.comI guess you guys didn’t follow the link to Yahoo! Searchmonkey. Spiders are not the only way Yahoo! finds data anymore. Any site may provide structured data and customize their result set as you saw in the SERP above.
BTW, Reuters has a tool to help you format your data for Searchmonkey:

http://www.mysqltalk.comOh, now I get you. I thought you meant the links on Wikipedia are nofollowed. You mean on the SERP itself…
