Getting deeper

Having explored items 8 and 9 of 23 things, I'm wondering if there's room in my brain for what's left to learn! The RSS feeds concept looks useful for very specific interests, but unfortunately when I looked for the RSS symbol on several websites, I couldn't find any. However, I did save an interesting blog under favorites in my Bloglines account. But it's good to know what that all means for future reference...and the MERLIN site has a veritable wealth of links!
