Ive gotten paid more on my steem posts so far than most musicians earn in royalties across a decade sooo I doubt im being shortchanged
I'm going to join @seanlloyd in playing the devil's advocate here. :D
The shortchanging is especially significant when you have a post which tends to rank very well in search engines and continues to get both traffic and upvotes for months after the rewards window was closed.
With the ever-growing Steem ecosystem this is going to become a more often felt sentiment as well. Two platforms where the 7 days window may be shortchanging would be Steemhunt (upcoming ProductHunt on the Steem blockchain) and any Q&A project like What Q&A (apologies for link to own article about it but the Steem account of the project is less detailed in info IMHO).
In both examples, there is a case to be made for the content to have longer lasting value than the 7 days window. A solid product (say Vessel) is a solid product, not merely for 7 days. Same applies to a great answer to a question.
Both should be able to continue to be rewarded.
But dude there is no mutual exclusivity between these options. You can list up all of your music across all of the traditional platforms - Spotify and Apple Music and all the rest, you can be on YouTube, you can do a music video, you can mirror or provide alternate content on your own blog with your personal website getting the SEO juice.
I see absolutely no conflict between these things. All I see is an additional income stream via the Steem blockchain, in addition to everything you could have done prior to 2016.
I'm not limited to music though.
In fact, neither of my examples were music related. We are talking "Steem could shortchange", right. Not about all else you could possibly do.
