Possibly Orphan Page
Links to this page all use rel="nofollow".
This page is intended to test another hypothesis. Namely that a page to which all incoming links have rel="nofollow" will not get crawled and indexed by Googlebot.
There are links to this page from several pages, but all use rel="nofollow". It is not blocked in robtos.txt. We shall see after some time if this page gets into the index or not.
