I once asked myself if I would be willing to pay for access to ZH and my answer (to myself) was no.
The reason is simple. ZH articles are not why I visit the site, its the informative comments and views of other ZH readers.
PS: ZH has morphed (over the years) into more of a "click bait" website. True journalistic investigation of an issue was done in the past but not anymore. The Tyler's obviously have to pay their bills and so I will not complain of this change. There is still some merit in what they publish but again the true magic of the site is it's diverse reader base.
