Content is like a baby. You watch it grow slowly and this makes you happy. They don't always grow out to be hot shot doctors (front page), but regardless you're still proud of them. However, during the early stages of birth/submission, they are susceptible to tumours (red thumbs). You can choose to let it continue to survive on in hopes of the surgery being successful, or end it mercifully (deletion). And sometimes, the kid just goes through life being ignored (a million views, but three thumbs - you know who you are).
