Hey, I think you are right about the "ease of use" of steemit. Altough developers are working very hard on the internals of steemit, I sometimes wonder how much work goes into user experience and design.

Also don't forget though that steemit.com is still in beta (which means it's testing phase). I personally think it will be a very long time (one year and more) before steemit will have the same ease of use as any other social media platform. Once that happens, organic growth will slowly take over.
