We've written quite a few posts about sharing information from RSS feeds (see RSS tagged articles) from allowing people to subscribe by email to displaying content of your feeds on your web site.
I think one of the simplest ways has been overlooked - that is creating a Bloglines account containing the feeds that you want to share, and setting the 'Show My Blogroll' option in 'Options/Blog Settings' to 'Yes, publish my Blogroll'. The NHS National electronic Library for Medicines have created a Bloglines account to do this. My own account can be seen too at http://www.bloglines.com/public/pfh.
This gives an easy way to allow people to keep track of a set of feeds by visiting your page. Alternatively they could download the OPML file containing your subscriptions (by clicking on ' ') and upload it into their own Bloglines account. This would allow them to add and delete feeds to suit themselves.
If you're interested in following peoples thoughts on using technologies in teaching and learning why not download my OPML file, set up your own Bloglines account, upload the OPML file using the ' ' link and delete the categories and feeds that you don't need. That's a quick way to get started building a library of RSS feeds of your own.
