Multiple things actually. One of the bigger issues I have with dragging people over is the long wait time to get a free account. I tell them it's a blogging and social media platform and that there are services attached to it via third party developers to make it like twitch, youtube, pinterest, reddit, pornhub, etc based on their interests and their interest in monetization of their content.

And among the first thing they tell me is "yeah, wait time is too long or I have to pay for instant? Nah forget that".

Then there's other bits like how much of a pain in the royal ass it is to actually invest into the platform itself so it definitely needs listed on more exchange sites.

I'd also argue further that Steemit itself needs to expand, not just using the IPFS system but going further it needs to allow for video and audio uploads so that one doesn't need to use a third party service in order to get that functionality.

I also agree with a lot of what the other commenters have posted.
