9. Wikipedia as the front matter to all research

10. “Wikipedia is not the bottom
layer of authority, nor the top,
but in fact the highest layer
without formal vetting. In this
unique role, it serves as an
ideal bridge between the
validated and unvalidated
Web.”

36. Linking is a small act of generosity that sends people away from
your site to some other that you think shows the world in a way
worth considering. [...]
[Sources] that are not generous with linking [...] are a stopping
point in the ecology of information. That’s the operational
definition of authority: The last place you visit when you’re
looking for an answer. If you are satisfied with the answer, you
stop your pursuit of it. Take the links out and you think you look
like more of an authority.
