I found this post very informative.

I believe mostly that people expect this platform to be exactly what they're used to, like facebook, twitter etc. and they may get sidetracked with all the content on the other platforms.

I personally am waiting for the day we have an app on our mobile devices where we can take a picture or video on the mobile device and upload it directly to Steemit without a third party. (I know there are probably dev's hard are work on this, and I offer myself a tribute to be an iOS tester )
