It is depressing how bad Wikipedia's content on computer-related content is. Tonight's exemplar is MOV (x86 instruction), an article on an entire category of instructions in the Intel x86 instruction set. The article has just about the ugliest formatting possible in MediaWiki, and does an excellent job of imparting information only to those who already know it. Finally, it's entirely unsourced.
I frequently find myself, after reading computer technical articles in Wikipedia, left with the impression that they have all been written by students who have just learned the material themselves; they are written with only the most superficial of understanding, and with none of the rich connections to related topics that one would hope for in a general-audience encyclopedia.
This page is not an encyclopedia article; it is a page out of a quick reference handbook, and a bad one at that.
