Nice video.

I would end the presentation with the world: rewarding...so you have "Simple" then "Meaningful" then add "Rewarding".

I would also bring the reward side of things a bit more to the front of the video. First couple of sentences shall bring the unique value proposition of ESTEEM8/Steemit in front. Also, I would not mention to many obvious things, all the different post catgeories you mention takes most part of the preso, but is not adding anything. People will know what Social Media is. See also the comments by Hive account@cryptoctopus, he uses different words for the same thing I try to explain.

BTW, are you planning crowdfunding by asking donations, or will you in the end have a premium model using your frontend to Steemit, ie a dollar value to be paid before able to use your software?
