I don’t know about whether they never appear in Google Webmaster Tools. I think I have had–like I think the Google blog has me on the blog roll or so mething, so I’ve seen some links from Google.
But, in general, people hold Google to a very high standard. You know, if we have search results that are not blocked by robots.txt, people find out, notice, and let us know, and, you know, blog about it, and it drives a lot of attention. So, we try to be relatively careful.
You know, things like search result don’t flow page rank within Google, most Google properties, we try to make sure that they’re not too spamable, and if we’re worried that something might be potentially abused, then often will use a nofollow attribute.
