Web 2.0 and RSS

I learned that RSS is a tool is a family of web feed formats that are used to update you on certain sites about what is happening on that site and the newest news or updates on that cite. As a future teacher I can use RSS to give me update on educational websites like NASA or even my GoodReads account. I learned that their are many different kinds of Web 2.0 tools out there that can be used. The ones we learned to use in class are delicious and goodreads. Web 2.0 tools can save a future teacher a lot of time and energy. I can have all websites that I find important in my delicious account and can access them all easily from there.
