There are lots of ways to keep up with your RSS feeds - online, in a desktop reader, in a program like Newsgator's Inbox 3.0 which integrates into Outlook, or even just in Outlook itself. That last option is especially useful if you work in a company that doesn't allow you to install software on your computer, like a desktop reader, or maybe you just don't want to appear as if you're surfing the internet every time someone looks over your shoulder. (This blog I'm reading is work-related, I swear!)
Outlook 2007 has RSS feed reading built right into the software. Besides being able to subscribe and read your feeds in Outlook, you can also share interesting feeds with your colleagues, too - just right-click on any feed and choose "Share This Feed." An email will be automatically created with a link to the RSS feed, so the recipient can subscribe as well.
