The RSS Reader.
I pick up on stories much quicker now than before. I have two subscriptions which are pure news feeds. One is a news from the Philippines feed and the other is a world news feed, both are created by The Philippine Times.
Also, I don't waste so much time now d'loading the full content of other blogs, I see a story that appeals to me I can pull it up in full otherwise just nevermind.
Those two feeds I describe above account for quite a few Blogger Beer words today, I am very glad I have them.
