Yesterday was a very big day for blogging and podcasting -- particularly for those of us using these new media vehicles in PR and overall corporate communications.  Do you know why?

The reason is this: IE 7. 

IE 7 is the new version of Microsoft's Internet Explorer Web browser, and it's big news for us because it includes RSS feeds.  When browsing a page that has an RSS feed in IE 7 you can see via a lit, orange RSS chicklet that there is a feed, subscribe to the feed, and look at the feed updates right in your "favorites" window.
