RSS feeds

Just learned about RSS feeds and subscribed to a few ,,,, have seen that little orange symbol on many pages  and knew what it was but never actually did anything about it.  This 23 Things program is opening my eyes to potentially new ways of doing things in my work and personal life.  For ex: instead of sending out emails to my faculty about trials, new services, notifications, etc., should I set-up a blog and encourage them to subscribe to that?  Though not sure how many of my faculty would do this.  Perhaps it is worth a try while still using the old method (email) to push-out information.
