This could work unless and until Steemit loses search engine credibility. Then we'd have all these links to a failing site dragging us down.
Incidentally, I posted a few articles on Hive about my art and posted links from here to my Etsy site. Almost immediately, my Etsy traffic went down. When I saw this was a trend, having a little knowledge of SEO, I deleted the links and my traffic started recovering almost immediately. It's really a shame, because here is where I write about my art and I'd like to link to it, but Hive's credibility at the moment does more harm than good, and I can't afford to lose the traffic.
