Search engines don't totally ignore links with a nofollow - they still crawl them, they know they're there and they still affect PR calculations.
That's some really bad information...
... matt cutts made it pretty clear on a video just last month - and he was talking about nofollowed wikipedia links:
Do they keep stats on rel="nofollow" links, just privately held data? I'm sure they do. Even in the video, Matt mentions that nofollowed links make up a very small percentage of all links on the web. So they watch it, and they know about it - they just don't evaluate urls based on it. Google doesn't even use nofollow links for url discovery.
Google does NOT use nofollow links.
The only way a nofollow link 'counts' at all is as a link on the page to prevent PR sculpting, so if you have 10 links on a page and nofollow 5 of them, the 5 followed links do not pass extra weight. That's it. That's all. Nothing else.
