Right now you can find tags for a post on list page (e.g. https://jenkins.io/node/page/2.html ) and you can filter all the posts by specific tag (e.g. https://jenkins.io/node/tags/tutorial/ ). But you can't see post tags on a specific blog post page. It could be useful, people could read the post and find similar posts by clicking on a tag at the bottom of a page maybe.
