I go to a lot of sites every day for news and the rantings of political junkies and interesting people who write.
At one site you have to hit the back button twice instead of once.
At one site you have to click on a blank space in the body before you can move around the page. Another where doing the same thing activates a link to an enlarged version of a nearby picture.
At one site the up and down keyboard arrows and the mouse wheel don't work no matter what you do, and you can only move up and down the site by clicking on the right side navigation bar.
The HTML mark up is done by machines, without human intervention. Humans only drag and drop, cut and paste. And monstrosities are created. The simplest little bit of web real estate has thousands of lines of HTML where dozens could create the same look.
And that's massive unnecessary overhead. And it causes stupid effects like those mentioned above.
And you kids get off my lawn
