People who design things don’t actually use them… and expect that others will want to use them. Web sites are the worst.
Like today, I was on a comic web site… the comics are great… they have this really cool “Random Comic” link at the top of the page, and many of the comics are much longer than one page. You read the comic and have to scroll back to the top of the page to hit the Random Comic (or any) link. If you want me to read the comic and stay on the site, put the link at the bottom of the page so I don’t have to scroll back to the top to view another. If the web designer had actually used the site, they would have realized that putting those links at the bottom of the page would have improved site usability 257%.
