There are a lot of issues holding back steemit. As a platform, everyone you wrote is correct, but there are also some fundamental issues that are holding it back. I have been conducting various experiments over the past 6 months to prove a point and my point has indeed been proven. I truly hope Steemit makes it through. I think Steem is a great blockchain that offers a great many opportunities. My fear though is that Steemit will not last. I think the platform is proving its own point much like myspace did prior to facebook. Other platforms are already coming on the scene. None have what Steemit has to offer or the user base as a support but that doesn't mean another or others aren't coming that will. Steemit can't change fast enough I fear. But, hopefully I will be wrong.
