Interesting. Wiki in Hawaiian means fast, quick or swift. Is it as fast as that? Don't know. Will check it out!
Yes. Somewhere in the credits I saw that the name is from the Hawaiian.
The Wikipedia is user modifiable/correctable. That makes it 'fast' to adapt but as Chris SI points out it means it can be modified or added to on occasion by people with bad facts. Or maybe bad agendas. That was sort of one of my questions on this thread.
Does the flexibility allows for too much corruption or bad information? Enough so that it loses value as a source?
