I saw an article today which talks about the effect RSS will have when combined with the clout of Internet Explorer, since Vista is the first OS to have IE7 and RSS support built-in. While I think that the writer is overstating the impact RSS will have on computing and the Internet with the launch of Vista, there will be a little effect I'm sure. Most of the computer-savvy people out there are using Firefox anyway. The rest of the article talks about neat stuff you can do with feeds. Here's the link to "Supersize your RSS."
There are also Firefox extensions for RSS, including Wizz RSS which I just installed and am playing around with.
Someone asked me what feeds I subscribe to. Well, I don't have a lot of blogs subscribed just yet, but I am slowly but surely getting a list of blogs and will be adding them to my RSS list as well as my Links sidebar. I took this screenshot right after I saw that first comment.
