Thing 8--Tagging

Tagging is very useful. I think this compliments subject headings, but doesn't replace them. Tags are much more interesting to look at than boring old subject headings, and allow the tech savvy the ability to quickly access popular information.  Plus, this can help you when you are not sure what subject heading a topic might be listed under. Oh, and the large words often grab my eye, causing me to search something I was not even looking for at that time.
