Tags
Below are the currently popular tags, by category.
Tags are simply keywords that describe the items added. By clicking on any of the tags below it takes you to articles which have been given that tag. It is also a useful way of letting the system alert you to articles of interest. In my profile you can give yourself tags (see foot of page). When new items are added to Gwagle and they match your own tags they are added to your 'My Interests' section.
