A few months ago, I had no idea what RSS feeds were and why I needed them in my life. But now that I know about them and use them, it's great!
RSS stands for Really Simple Syndication. For a more formal definition, see here. But to me, it basically tells me when something that has new content frequently (blogs and such) has something new for me to read. You can read the new stuff in a reader, via email or via a side bar thing if you have IE. Before this, I would have all my blogs in a folder and click through each link daily, wasting a lot of time. But now, I just click over to feeds and see which ones are highlighted (meaning has new stuff to read) and read those. Great stuff!! Anyhow, just thought I'd share this with you, though I'm sure a lot of you know about this already. :) Cheers!
