@bmacfadden – This is a great development!
Regarding your question about “Tags,” as Eric has mentioned before, they are simply a way to organize posts. Here is some language from the WordPress.com support site: “Tags provide a useful way to group related posts together and to quickly tell readers what a post is about. Tags also make it easier for people to find your content. Tags are similar to, but more specific than, categories. The use of tags is completely optional.” On our wishlist of updates/improvements, we have asked Eric to add an explanatory note beside the “Tags” field so that users know how and why to use it. Hope this is helpful!
