I think Steemit in istelf is a great way to introduce Steem. I actually just did this very thing a couple of months ago when I was talking to a group of people.
A lot of people have a hard time wrapping their minds around the idea of blockchain and crypto currency. They just can't understand where it comes from and how it exists in the first place.
A blogging platform though, I think a lot of people can understand and wrap their minds around that. They can go to a website and see blogger or whatever in action. Likewise, you can take them to the Steemit site and you can have them see what it looks like in practice.
This person posts a story, other people upvote it, and it earns money. You don't need to understand the economy and everything that goes on in the background to understand that.
Outside of Steemit, I think the best way to introduce someone is to show them either the Partiko or the Esteem applications. It is just a smooth interface and an easy way to view everything that is going on with STEEM. If they aren't that interested in blogging, you can get them setup with a Steem Monsters account by buying a starter pack.
That is another great way for people to be introduced to STEEM. Even if they can't understand the concept of cryptocurrency, they can probably understand the idea that the game cards hold value and you can sell those cards or upgrade and use them if you want to.
Those are a couple pretty easy ways to bring new users and people that might not be able to easily understand crypto currency on board.
There is no real easy way and best to get them to register first. Once they have registered you can then explain with a hands on lesson. Letting someone loose will only confuse them and maybe even give up.
I have just done this exercise this week with an old friend. He has been doing blogging already on another site ,but the whole reward system was new to him. I compared it to playing a game where you have to build up SP to unlock new levels. This was the easiest way to explain the Resource Credits.
There is going to be another follow up lesson this weekend so I should get him onto a few other things which I asked him to look at. i expect loads of questions which is great. He will remain on the site and grow as he understands how to grow. Understanding this is what will increase retention levels. I am sure you will see him on musing very soon as I will be showing this side in the next week or so.
Introducing Steemit and Steem gets fun especially with the integration of DApps with diverse uses to enhance the experience on the Steem blockchain. Here are my suggestions on how to introduce Steem to people.
1. Show them love with gifts or free services courtesy of Steem
It's no news that though the price of Steem is low, users can still utilize their earnings no matter how small to impact others lives. This can be done through charity campaign donations as carried out by communities such as @sc-v @steemchurch @sc-g @sc-n, @adollaraday @YouAreHope @writeandearn, etc. After such donations, make bold to say that the gift or free service rendered was paid in full by Steem which could be earned from Steemit.com, musing.io and other DApps
2. Direct them to get their problem solved using specific-purpose DApps
DApps such as https://musing.io/ https://dsound.audio/ https://d.tube/ http://utopian.io etc can be used for daily activities such as getting help, recording sound and programming respectively can be introduced to non-steem users to get their attention. Simply tell them that their tasks can be done in a giffi with those dedicated DApps.
