I prefer tumblr more than twitter or facebook. Since I'm a bit poetic, I like expressing my thoughts through my writings. Tumblr allows that. And unlike twitter, most writings there were actually more focused in what a person views in general (life) than most one liners on twitter that doesn't relate to anything worth noting. That's my opinion anyway. Haha.
Does Wattpad count? Anyways, I love how stories are free, and very accessible. Always when you can write too as well, writing and reading put together so easily is a dream come true. Had a wattpad account for a few years now and I still love it. ️
