While researching an error code today, I found a site that documented the issue and posted a solution. However, the site kept popping up a “talk to an agent” nag screen about every 10 seconds. “No” I muttered, “let me read your f****ing website”. After a minute of so of this, I finally closed the site and started looking elsewhere.
Point: don’t make it impossible to interact with your content. Jeez!
