Not only can tags can be helpful when looking for something specific, the ones in this blog will help narrow down people, places, things and ideas. And since there can potentially be hundreds of tags, they have their own page. So just click on a tag to your right (below for cell phone users and some on tablets) to see posts related to that tag.
Please know that tags are subject to change and may be periodically added to a post or removed altogether.
I guess I need to say that because I am still learning!
