Really? I was always under the impression that PageRank got its name because, you know, it ranked pages. Is there more of a story behind the naming?
The basis of Google's search technology is called PageRank™,
and assigns an "importance" value to each page on the web and
gives it a rank to determine how useful it is. However, that's
not why it's called PageRank. It's actually named after Google
co-founder Larry Page.
The explanation is similar to the name pg gave to the markup language for Viaweb, RTML:
>We made up various explanations for what Rtml was supposed to stand for, but actually I named it after Robert Morris, the other founder of Viaweb, whose username is Rtm.

Of course, that could just be some Google humor. I would guess that PageRank is named for the obvious reason, but that it won out over other names for the connection to the co-founder.
