Twitter has a Favorites feature. While you can use it to collect funny or insightful posts, it's also a great way to keep track of things you want to read later. If you mouse over a message, a star appears on the right; click that to add the post to your Favorites, which appears as a list under your Favorites tab.

This trick can be especially handy when you're on the road using your phone, and you want to save a link to read later on your PC. If you're using a mobile client (discussed later in this chapter), you've almost certainly got a built-in favorite feature. If you use Twitter via SMS, you can reply to anybody's last post with the command FAV username to tag that message as a favorite. For more text commands, see Chapter 1.
