I think it really depends on what specific aspect of Steem you know will appeal to the person you want to bring in. For example, for me, with the music, I might say that there's a really collaborative group of musicians that only hang out on steem or do steem exclusives/hear it first on steem... (I'm still trying this out).

Another example is the little contest I am Co-running called @yourtop3 where we share on twitter what people's top 3 things are on a specific topics then ask the twitter folks if they agree with a link to SteemPeak (still trying out different ways again).

Travel posts, I only share travelfeed blogs as I want to direct people to that interface and they have created "easy log in" but I don't have any figures on how many "eyes are on" so to speak.

Basically, I guess I'm just trying to get like minded folk together a bit like what communities are offering without mentioning it. We'll just have to keep experimenting 😀
