This is a great site to learn about how to tag.
Tags
Users add tags to describe online items, such as images, videos, bookmarks or text. These tags are then shared and sometimes refined. For a more detailed definition of tags, see the Wikipedia entry here.
Here are the examples I showed you in the screencast, using the tag “sharpie.”

Step 1: Discuss Tagging Policy
Tagging can get sloppy – spelling errors, verbs v.s. nouns, etc. You probably noticed that about my tag stream. This can make trouble down the road if you want to publish your resources to a web site using an RSS. So, come up with a few standard tags. But don’t get bogged down – you’re not creating a formal taxonomy, rather it’s a folksonomy. Also, people can add whatever additional tags they want so they can remember the item as well as a description.
If you want to understand more about tag strengths and weaknesses, I recommend the following articles:
