For Mac Users
I love using my Google Reader. I subscribe to multiple Blogs, Twitter & Facebook accounts, Websites, & more. It would be extremely inefficient of me to visit all of these sites multiple times a day to read the updates. Now the updates come to me. I also create alerts where I tell the reader some keywords I am looking for. When the reader finds these keywords it sends an update to the reader.
I suggest exploring these tools and begin using the reader that best suits you.
