Sometimes when something's difficult to use, a person will respond by thinking "what is wrong with this thing?" That's the normal response. But even before our wares became soft, some people had a different response: "I'm bad at this."
It's what happens when a function plays hard-to-get. And since, I'm hoping, completing some minute task like adding something to a shopping cart isn't likely to stimulate your innermost desires, it's not likely to get much of your time, either. On the internet, the place of limitless alternatives, tasks that play hard-to-complete on sites that play hard-to-use end up making the site hard-to-finance because profits start playing hard-to-get because the users got got by the competition's Betty Cooper of websites.
So there's these two forces at work - some people can see what's happening and get out before the abuse continues, and other people still assume it's their fault. It's been reinforced since they started using computers and the internet. But just like abusive people, bad sites tend to end up alone. Even similar sites won't link up with them! They're just too frustrating to use. People go elsewhere for the same info, and nobody makes any ad dollars.
If your website is causing someone pain, it's important to get it some therapy before it keeps hurting your business!
