Tagging is a simple concept with great power. Tags are similar to bookmarks (or favorites, in Internet Exporer), but they are also so much more. Tags are central to the new social media and web pages in the last few years.

Tags are labels. You can put as many tags on a web page as you like. That way, when you search for information, you can get different lists of web pages depending on the key words (tags) that you use.

Email, for example, in Google (called Gmail) is not put into folders to organize. You tag the emails you are interested in, sometimes with 3 or 4 tags, and then you put all your emails into one folder. It is easy to find simply by searching for tags. Tomorrow, I will show you a specific web site that does tags.
