There is no strict dictionary definition of an "encyclopedia." It's a broad category which includes works which have original research, which aren't organized alphabetically (or even with specific 'articles'), which are written by experts or by non-experts, and so on.

Nothing in what I said was meant to suggest changing much less gutting Wikipedia. It was to say that the concept of an encyclopedia is very broad, and includes both Wikipedia and encyclopedias with policies which are directly counter to some of Wikipedia's policies.
