Facebook! 

As much as I love to say Steemit, right now I am definitely using Facebook more. 

As a social media platform, I think that Steemit will lose big time against Facebook because of the strict policing on "spam" and thrashy contents. Facebook might not be decentralized but it feels like you are more free there compared to here. 

In Steemit, people are highly encourage to post long blog posts and deliver exceptional contents which is very unlikely for a social media platform. Plus, with user account creation so slow and/or needs payment. it is impossible to invite your in-real-life friends in here. So right now, I am using more Facebook than Steemit because my irl friends are still on there. :)
