Agreed, I think forcing lower case is required to prevent canonical taxonomies, but they could display as capitalized on front end using css: .TagList__horizontal a { text-transform: capitalize; } 

The post editor could easily transpose upper case to lower, and that is a great idea @thoughtchain.

Another change I would really like to see is the addition of target="_blank" to all external hyperlinks. Really I don't see why they have to open in the same tab as our post.
