What it is:
What you need:
A tagging application. These are usually free, third-party applications such as Delicious or AddThis. Other applications have internal tagging functions. MiddTags is an example in this website. The photo-sharing site Flickr is another example with internal tagging. Most blogs also have an internal tagging function.
How you do it:
Simply choose a term (or terms) for the thing you want to describe, and apply it using the internal or third-party application. These tags will appear in a tag cloud or other search interface for retrieving tagged information.
Tips and suggestions:
- Use as many tags as you need to classify something. If you can't decide among several tags, use them all.
- Most tagging features have a suggest or auto-complete function. Use it. This promotes consistency which improves retrieval.
- Tag immediately. Otherwise, you'll never be able to find that "great thing" again.
