Steemit, Busy, ChainBB, DTube, DLive, etc. are really just pretty blockchain explorers. They look at transactions on the blockchain, render the markdown contained, and that's really pretty much it. The entire Frontend world of Steem is still in the wild wild west - tools like SteemConnect are making it much easier for developers to get started. Take a look at netuoso's https://decentmemes.com - small dApps like that are starting to spring up all over the place. Developers being able to set themselves as beneficiaries and stake a % claim in all rewards made on their platform? Huge motivator. The possibilities of this are super exciting - imagine a Steem community with real mods, people who can actually ban awful content. Sure, you can still post to the blockchain and appear on Steemit, but if you've been posting terrible content to MyCoolSteemSite.com, then they can just not show your posts there. I predict within the year that Steemit will start to lose more and more of its majority share, and within 2 years most platform growth will come from new sources.
