Most wikipedia articles are not "informative and good as an introduction into a topic" - the sourcing is routinely biased, and important countersourcing ignored or minimized if included at all.
Oh yes, so true. Thank you for saying this. This discussion is dangerously veering into the politically correct. Wikipedia is much worse than this talk makes it look. Thanks for talking about the totalitarian power (ridiculously "petty" as you aptly put it) exterted by wikipedia admins. Wikipedia is a trap, a trick, a propaganda machine and a totalitarian project. The way power is exerted in there, the quotes from its CEO, everything concurs to this conclusion. Appearance of freedom is the bait (appearance of network-power-structure), hidden pyramidal power structure is the claw.
