I actually enjoyed this debate quite a lot. Vays is biased and possibly sometimes uninformed, but the whole exchange still comes across pretty meaningful. A voice of an uniformed sceptic is in my eyes valuable, leading the conversation in different direction from the one you would ideally like to see, but still a lot of interesting points are getting addressed.
Being in Vays' position, I would certainly spare anyone my personal opinions on Dan or other people involved in Steemit, which is what happens when he is projecting his impressions of Bitshares onto Steemit, tying them to the authors. Serial entrepreneurship is constant trial and error, and judging someone in that manner is actually a big giveaway of biased judgement. Fortunately Jeff is pretty quick to point it out to him.
