Thank you for the invite, although I still don't get it fully myself, so I probably can't be a lot of help. However, as a creative, this is how I understand it, and you may draw some useful points from it.

1. Steem is created -- mined -- by the publication of creative work; that is, people come and bring their writing, their music, their art, and in return, value is created on the blockchain. It is the nearest thing to the "Art Exchange" no less a person than Beethoven said needed to exist 200 years ago that has ever existed, with the caveat that of course, the value getting back to the artist is not exactly guaranteed. The artist does need some human curation -- appreciation -- for their work, which brings us to...

2. Steem Power, the form of Steem whereby a creative goes from merely bringing their work to the blockchain but also adding value to the work of others through an increasingly powerful upvote, and receiving a dividend for doing so. Through the accumulation of Steem Power -- or by converting Steem to Steem Power in a powerup -- creatives bringing their work to Steem change their position from one form of interacting and adding value to the blockchain to a second form: multiplying the value add by supporting the work of others. Which brings us to ...

3. Delegation: the act of temporarily sharing Steem Power with someone else in order to enhance their ability to EITHER bring more value to the chain by being able to post more often (that was my story at first), OR to enhance their ability to give support to other's work and reap a dividend, OR BOTH.
