Thanks, Peter :) People really enjoyed the presentation and many of them hadn't heard about blockchain technology before. After the presentation one person said that they were still having a hard time wrapping their head around what blockchain technology was because it was the first time they had ever heard of it. I felt good for introducing the concept to some people for the first time.

I've since had a chance to chat about the blockchain and specifically steemit with a few other people and all exchanges have been positive so far. Sometimes potential dangers related to security & other issues come up in the conversation, which is natural, but overall, the people that I've been talking to seem genuinely interested.
Yes, I think you're right....new technology is often difficult for people to trust/feel comfortable with and this is no different.
