Google “Authority” Implications: Google good for quickly finding non-
controversial, authoritative sites(eg: a movie home page)
Google bad for quickly finding factual information on controversial topics(eg: Israel-Palestine conflict)
Skewed results towards “page spammers,” “content farmers,” and commercial / Google-owned sites
