I've finally developed and implemented a set of categories for this blog. The main purpose of using categories is to help readers, especially new visitors, more quickly find the subject matter they are looking for, now that there are more than 70 posts on the blog. For those willing to scroll down the right-hand margine, I've left the long list of tags.
Even more helpful than categories in finding information on this blog is the Google search function that I've recently added. Check out the powerful tabbed functions of this search utility! Your suggestions for additional improvements are welcome.
