Well, before this Website there was Experience Project, which mainly was a place for people to be open about their kinks and sexualities and fetishes and experience. Or at least that was a prominent part of that website back then. Which I understand, when being open about such things, also when u cant really live them in your actual life, you probably wouldnt like to attach actual pictures of ur face to posts and stories here. When Similar Worlds was introduced alot of those people were driven away. In general most people nowadays think this is some kind of Facebook 2.0.
