On the other hand, articles written by experts with full detail is much more useful to those already well versed in a given field. To use myself as an example: I would look elsewhere for computing or linguistics information if the articles were all written for beginners.
I don't disagree with you - the articles are not at all useless in topics for which I am well versed. Like I say, the issue that is perhaps unsolvable is some intuative way to have the article useful to everyone at once while not bogging them down in useless info
