First of all I explain them a bot about blockchian if they haven't heard of and especially about Steem, the blockchian, then I explain them what a cryptocurrency is, how are they used and exchanged and so on.

Then I show them my blog with examples of my posts, interactions and how does the blog works. I make them also some analogies with other blogging platforms or social media platforms. I also explain them the benefits of using Steem in comparison with other platforms.

I usually explain more of my experience on Steemit rather than letting them to read the trending page and get the wrong idea about how things work with Steem. Of course, when tackling this topic I mention also about bit bots, upvotes and reputation score. 

The main idea is that Steem is the best blogging/social media platform built on a blockchain that rewards users, through upvotes, with Steem tokens. Plus I always encourage them to focus on quality rather than quantity and engage as much as possible with other users.
