Awesome!
Besides the changes on canonical URLs, are you also planning to improve the Steemit.com editor with regards to SEO any time soon? It'd be great for content creators to be able to manipulate the meta information of blog posts such as keywords for instance. Currently blog posts submitted via the Steemit.com editor don't contain any meta keywords at all. Also instead of automatically converting the very beginning of a post into a meta description it'd be much better to define it independently from the content.
I'm no software developer, but I think adding a form where to define the meta tags should be easy to implement while it could have a considerable impact on organic traffic.
Thoughts? :-)
