I heard it this way once: You open the paper and read an article about your field. “This thing is crap, they got all the details wrong and are drawing ridiculous conclusions!” Then you click to the next article, about something else. “Wow, this is really fascinating. We need to do something about this!” ... I think this idea has a name, though I don’t remember it.
If I said well the people who comment on here and the articles submitted here about fitness are mostly shit, why would I read their opinions about programming, then I'd miss out on a lot.
Not all the writers on staff at any publication are going to be bad, but some will be or they will just be given a topic to write about which they are not familiar with, but are experts in a different field perhaps.
