Try OS X Panther Discussion for size: it's a Google query for OS X Panther discussion. In what must be a record, Google is - at time of writing - returning empty Trackback pages as No.1, No.2, No.3 and No.4 positions. No.5 gets you to a real web page - an Apple Insider bulletin board. Then it's back to empty Trackback pages for results No.6, No.7 and No.10. In short, Google returns blog-infested blanks for seven of the top entries.

He is wrong - this is a consequence of Google giving strong weight to the <title> tag, over and above the PageRank involved. I believe they did this to reduce the alleged blog pollution he rants about interminably.
