What are some examples of tagging?
You can use tags describing an article or website’s subject, location, name, category, people, places, ideas — pretty much anything you can think of. The more tags the better! (Most people end up adding two to five tags to each of their bookmarks.) The only limitation on tags is that they must not include spaces. So if your web page is about a two-word place like “San Francisco”, you may want to tag it as sf, san-francisco, SanFrancisco, san.francisco, or whatever else makes sense to you. You don’t want to use commas, though, since a comma will be become part of the tag. You can also use tags to describe metadata about the bookmark. For example, you can use asterisks to rate bookmarks. So a tag of * might mean an OK link, *** is pretty good, and a bookmark tagged ***** is awesome. Other common tags include toread, or via:friend. Bookmarks that you want can be tagged wishlist, and ones that might not be safe to visit at work can be tagged nsfw. A tag can be anything you want.
