I definitely helps that's why I have voted it to top. It is a nice little summary of reward distribution. I covered such a brief summary in the Steemit economy post.
Suppose your post shows $100 reward. Upon payout, you (author) will only get 75 % of it (that too half in SBD and half in SP). Rest of the 25 % is converted to SP and distributed among people who upvoted your post (curators). For $37.5 (half of 75 %), you get exactly 37.5 SBD. The other $37.5 are converted into SP as per current USD price of Steem (you get as SP whatever number of Steem can be bought with 37.5 USD).
However, the information other than distribution is what makes this post a one stop shop for information Steemit reward system. That's why the length and the detail.
