RE: What topic would you choose ?

I think I would feel comfortable talking about Hive, but five minutes isn't even enough time to cover the basics about Hive. I've already invited a few people to Hive, and it took me a few days to help them understand the basics of how to create an account and post. Not to mention that I would still have to explain a lot about blockchain. But if I could talk about Hive in five minutes, I love Hive!
