Walsh feels that, eventually, the truth will win out and the revisionists will realize that it’s not worth the trouble:
“The reality is that Wikipedia isn’t a place for original research. It needs to be a proven piece of information before it can be added in Wikipedia… It’s a difficult medium to go in and say this is the truth when you have so many people watching the page making sure there’s no vandalism to it.”
Anatomy of a Wikipedia Edit
So how does Wikipedia get edited? It depends on the entry.
Wikipedia is a wiki, meaning that anyone can edit any unprotected page and improve articles immediately for all readers. You do not even need to register to do this. Anyone who has edited is known as a Wikipedia editor and, no matter how trivial the edit may seem, can be proud that he or she has helped make Wikipedia what it is. All those edits add up!
Some pages are however protected from editing. These pages have a View source tab instead of an Edit tab. You can still edit these pages indirectly, by submitting an “edit request” – an editor with the ability to edit the protected page will respond to your request.
You’ll notice that Wikipedia’s entry for Paul Revere, including a section on the famous “Midnight Ride,” is a protected entry. Therefore, any edits made need to be approved by editors with a bit more control than everyone else.
How do you become one of these super editors, which Wikipedia simply calls administrators? Per the site:
An ordinary editor can ask to become an administrator by submitting a request for adminship (RfA). The editor’s record and qualifications are discussed by other editors for a week, and the promotion is then decided by one of Wikipedia’s bureaucrats — a set of about 25 sysops at the top level of Wikipedia’s administration. The criteria that bureaucrats are supposed to look for include knowledge and respect for Wikipedia’s rules, steady and varied editing activity, etc.
So although Wikipedia is a site that “anyone” can edit, you can’t edit just anything—especially topics deemed important enough to be closed off to the general community by higher-level administrators.
