Digg, Del.icio.us and Technorati are websites where you can quickly and easily bookmark (save a link to) web pages you like, usually just by clicking a link on the webpage you want to "save", or by clicking a button in your browser toolbar.
Most of these types of websites will let you keep your links list private, and all you need to sign up to most is a working e-mail address.
Because your links are kept online, you can access them from anywhere on the internet. This could be really useful, for example, if you're researching coursework on the library computers and end up with a list of web links you want to review at home, since you just save your links online and access them again at home.
