I think that people need to decide what they want Steemit to be. I feel like some people are promoting it as the place to be for all social media, replacing facebook, reddit, instagram, etc..
The problem with that is that the majority of people on those platforms aren't interested in producing long form, detailed content, they just want to share the mundane day to day things, funny videos, meme's, pictures of their kids and so on. They try to post those same things here and are ignored because that is not the content that people are upvoting at the moment. They get discouraged after a few posts and go back to something more familiar.
