The Upworthy trick in making linkable posts by using certain headlines! Check out this slide show, especially slide number 7. I saw that yesterday and today I've spotted the Upworthy trick all over the Internets!
To be quite honest, I have sometimes used the reverse trick to make sure that a post I write isn't easily found by trolls: A long-and-boring headline.
Still, it's funny how easily I've been manipulated.
