I just saw one that took up 16 or 17 positions over 3 pages, yet oddly I do not see the effect at all in many niches where I'd expect to see it. Test?
The Matt Cutts video, which Brett posted at the start of this thread, clearly lays out the positives and negatives of host crowding, along with the negatives of dropping it... and I feel at the end Matt hints that this might be a test. I can imagine a discussion in a Google meeting room where the approach was hashed out, and ultimately the opponents said, "OK, let's try it and see what kind of data we get."
The video is interesting to see again in light of the new results....
How does Google decide when to display multiple results from the same website?
