1. It is free (unlike most subscriptions).
2. You don’t have to become a ‘member’ of this site.
3. I travel a lot and therefore postings are not always regular.
4. When you subscribe you will get an alert that a new article has been written.
Click on the Subscribe button (see pictured) to get article alerts coming to your computer via Google Reader, Bloglines, or however you manage your favorite web site feeds.
