Well, first, I reject the whole "suitable for a general encyclopedia" argument, because it's just not relevant.  Wikipedia is MORE than that, because it is not subject to the constraints that have bound traditional encyclopedias.  Size is irrelevant; I've got a half terabyte external USB drive on the Linux server across the room that is smaller and lighter than a paperback (well, Cryptonomicon at least).  Assuming good bitonal TIFF document images, that will hold 5 million scanned pages; assuming moderately compact text files (PalmOS reader format) that jumps to 250 million pages.  Printing costs are also irrelevant, since it's not printed, as are writing costs (monetary and temporal), as the labor force is both free and unbounded in size.  So it's back to first principles...
The definition of "encyclopedia" is a book or set of books containing articles on various topics, usually in alphabetical arrangement, covering all branches of knowledge or, less commonly, all aspects of one subject (Dictionary.com Unabridged (v 1.1)).  Since Wikipedia is unbound by the constraints of other encyclopeidas, then I truly believe that it should cover all branches of knowledge, and cover them far more thoroughly than has heretofore been possible.  As far as sysadmin topics go, Wikipedia failed me this week; if the article on Domain Name System had even so much as a link to resolv.conf, I could have save myself a lot of digging when I set up that Linux system.  In fact, I'll probably do just that, along with showing the file format of resolv.conf to that article, now that I've figured it out.  Why?  Because it's useful information that I needed and failed to find when I looked for it.  It's not quite "narrating the process", but it certainly is within the scope of an article on the DNS process to describe the steps taken by each part, and one of those steps would be "the client checks the list of DNS servers (see resolv.conf etc.) to determine which name server to consult"; that's all I would have needed to find the information I needed to solve my problem.
As Jimmy Wales said, Our goal...is to get a free encyclopedia to every single person on the planet. ...empowering people everywhere to have the information they need to make good decisions.  That's my guiding principle when I work on Wikipedia, and I feel that the accurizing article fits that perfectly.
