I had first heard about RSS (Real Simple Syndication) at a conference a few years back. Basically, it checks blogs and web sites for new posts, gathers them up, and puts them all on one page for you to see. It sounded like a great idea, but I never got around to checking it out. I wasn't even sure where to start until I took a class this summer. The text we read recommended Google Reader.
Log into Google Reader if you have a Google account, or go ahead and create an account. You may want to add the page to your Favorites or Bookmarks list. Open another tab or window and go to a web site you want to keep track of. Select and copy the address (it usually starts with http). Back on the Google Reader page, click the Add a Subscription box, paste the address, and click the Add button. It works for all blogs and news feeds, and should work for most web sites. Have fun!
