I have always imagined PageRank to be modeled after how academic papers are judged. What cites that publication, and who that publication cites, are quite important information to put a publication in context. For the same reason, I don't think PageRank will go away.

Two improvements that I'd like to see in search results are: (1) the ability to exclude particular domains from search results; and (2) the ability to over-weight certain referrers (i.e. a link from Encyclopedia Britannica is worth more than a link from Wikipedia, which is worth more than a link from MySpace.)

You are correct but in the scientific community there are no armies of spammers who persistently try to outperform other scientists by writing fake research papers and spamming citations. There are cases of fraud here and there but not at the scale of the Internet or to be exact the World Wide Web(WWW).

Google probably already does this but exactly how nobody knows because of their blackbox algorithm policy. Speaking about this suggestion; it depends on what you search query is....you need to assign specific weight values to certain referrers in relation to search queries from X,Y,Z categories.
