Wattpad is a pretty interesting place on the internet. It's all meant to be what people have written themselves. Unlike a lot of writing sites on the web it's not exclusively for or against fanfiction, so you'll find a lot of original stories and fanfic on the site, so long as they give proper credit to the author.
A lot of people hope to get published, most don't. A few authors I've followed, though, have gotten some pretty substantial book deals through site discovery. ~
