There's a difference between maximizing profit and making enough to run a respectable operation.
The better websites will post a lot of short, less than stellar articles to get search traffic and revenue, but still post good articles regularly. Ars Technica is a good example.
Ars Technica does have stellar articles and they are not so short... I just think that it is sad that the main strategy is maximizing profit through page views over quality and creative writing... maybe I am crazy but that's my point view...maybe the actual system is broken...
