The difference with Steemit is that to succeed you have to think about what you're writing. You can't repost someone else's meme and get credit. Creating valuable content is what the platform is built on.

The same goes for curating, I find myself reading entire articles on Steemit instead of reading 2 sentences and upvoting. I can't say the same about Facebook.

So don't feel bad you're spending time here, if you're doing a lot of reading and writing then this is good for you!
