Not really a problem of mine but I've just spent 45 mins talking to a guy who couldn't get my website. The guy was 80 years old, works in IT and has worked with computers for 26 years!
The reason he couldn't get to the site was he was searching on Bing and it was giving him the wrong results. So I said use the address bar thinking hell he's in IT and used computer for nearly as many years as I have been alive, he'll know what he is doing.
I didn't know how wrong I was, I swear he must have had less than 2.6 seconds of computer experience never mind years. Works in IT, you having a laugh right you don't even know how to use the internet let alone work with IT. I asked him to send me an email with a screenshot so I could see what he was doing and the guy couldn't even compose a god dam message.
I had to walk away from my desk and take a breath after 45 mins I felt exhausted.
