Voting for perceived overvalue is absolutely valid, but I'd say writing or recruiting writers to do better content is even better, and by better content I don't necessarily mean more strategically accurate. It may be simply avoiding the most egregious errors, as you put it, and still addressing a mass audience of more casual players (of course having more of the accurate more-strategic content is great too, and we have @daut44 doing a good job with that).

There is no one other than @armen targeting the casual player as far as I know right now, so heavy flagging of his posts without there being anything better is essentially killing the category. It is your prerogative, but I would personally rather see them earn a moderate amount (at some extreme point I would flag too though) and serve to attract others looking to do the same thing (better).
