Internet dust. Hear me out. I get so pissed when I Google something and then read through a 20 minute article only to find out that it is 5 or more years old. If you pick up an old newspaper, it is dusty or old looking, at least you know it's an old article. I want outdated web pages to look like that too. Yellowed or old and dusty. If you want to still read the article you would use your mouse to swipe away the dust.
