I think SEO on Steemit is a virtually untapped gold mine at this point. I've made several posts about adding anchor text/image links and alt tags for images and I've seen a few others who have begun to spread the word.
I can give links to the posts if you like (they're already past their payouts) but I didn't want to spam your comments with my links.
