I would counter that the expense of a thing should not be the overwhelming factor in its consideration. Just because something is expensive, does not mean it is not worth doing. Otherwise, we would all be huddling in mud huts and carting around cow dung for a living.
Agreed. Despite the poor architecture of the site, if you value the article itself, visit the original source. If you do not, the site receives less notice, less advertising revenue, and less funding. QED, less interesting articles for you to consume.
