One of the things I love most about the internet is how other people do things for me. Take, for example, sorting through thousands of images to find the best, funniest, coolest, most amazing things.
That's what virality does. If a pic goes viral, you know it has a stamp of approval for quality from thousands of eyes. People who look at the internet every day say, "Hey, folks, you all should see this, it's awesome. Don't bother with that other junk. This is worth your time."
Just like the pics below — they went viral, so somebody must like 'em!
