I wish I could wrap my head around the size of the subset in relation to the larger set of users of the internet. I think that those are able to accomplish this have a huge leg up in product design, and this ability is something that is incredibly taken for granted. One time my non-technical partner was attempting to access something I had been working on for a day or so and he told me that it wasn't working at all (even though I had confirmed it was before I had left) and I started to panic as we were close to a deadline for a client. Turns out that when i was telling him to access dev.somesite.com he was putting in www.dev.somesite.com and it was screwing up the javascript... because he naturally thought everything started with a 'www'. It blew me away that he didn't understand the concept of subdomains, but also it was a reality check that he sort of knew his way around a computer and websites, and that it meant there was a much much larger set of users that couldn't grasp the concept of a subdomain. It can be difficult sometimes when you have the perception (especially on HN) that so many people out there know more than you about everything. I guess you just have to take a step back and realize you are still in the 99th percentile of the rest of the world when it comes to this stuff.
