What are tags in del.icio.us?

Tuesday, November 04, 2008 Posted by Aman Jain

Most web browsers organize your bookmarks in folders and subfolders. Arguably the best feature of del.icio.us is the use of tags:labels or keywords that let you view your bookmark list based on single or combined keywords.
For example, to bookmark a web page that describes a foolproof technique for slicing a ripe mango, add it to your del.icio.us bookmarks and tag it mango,how to,kitchen,fruit ,cooking, and summer. One bookmark can have as many tags as you'd like.
If you also bookmarked a page with a great smoothie recipe and you tagged it smoothie, fruit,and recipe, the mango page and the smoothie page would both appear under the fruit tag listing. However, only the mango page would appear under the how to tag. A list of both fruit tag and summer tags would include only the mango page as well, because the smoothie page was not tagged summer.
To enter a set of tags for a bookmark in del.icio.us, you simply type a list of words separated by spaces. So you'd enter

smoothie fruit summer

In the tags field for smoothie page bookmark. The freeform nature of the tags field makes creating and assigning new tags extremely easy, but it also leaves the door wide open for misspellingsand similar tags(such as fruit and fruits). After using del.icio.us for some time, you will make suggestions from your tags as you type.
