Moritz Stefaner, Dario Taraborelli, and Giovanni Luca Ciampaglia:

As Doc Searls recently put it, Wikipedia is, like the protocols of the Net, "a set of agreements". A Web protocol defines the way in which computers communicate with each other and make decisions to ensure successful transactions. Wikipedia policies have the same purpose, but instead of transactions between machines, they regulate human decisions. An important part of these decisions bear on what topics are suitable for inclusion in Wikipedia and what topics are not. The present project looks into the nature and shape of collective decisions about the inclusion of a topic in Wikipedia.

Decius on Wikipedia, in 2003:

I've found myself using this more and more recently.

k, in 2005:

The handling of libelous or outright false content is something Wikipedia certainly has to deal with somehow. I think registration is an OK minimal requirement, honestly.

Andrew Keen, in 2009:

In the future, I think there will be pockets of outrageously irresponsible, anonymous people ... but for the most part, we will have cleansed ourselves of the anonymous.

Threat Level, in 2007:

Wikipedia Scanner -- the brainchild of CalTech computation and neural-systems graduate student Virgil Griffith -- offers users a searchable database that ties millions of anonymous Wikipedia edits to organizations where those edits apparently originated, by cross-referencing the edits with data on who owns the associated block of internet IP addresses.
