YES! I'm a huge fan of semantic tagging. How I'd like to see it work:
- Users add as many tags as they want to their post
- Steemit removes the 5 tag restriction
- When you vote on a post, your vote would count for only a specific tag - but you'd vote with your Steem Power, not just a +1
- You could specify a tag order when you search
- Travel Blog posts with Photos is a different search from Photos about Travel
Travel Post with Photos
Another issue that must be addressed: Closely related tags. There's a steemdev, steem-dev, and dev tag. How the hell is someone supposed to pick without picking all of them? Unless new tags are moderated and combined with some human intervention, there has to be a way to suggest tags for a post- or combine related tags into a super-tag of sorts.
