Thoughts about using RSS and some of the best links I found:

I found that using RSS in my blog is fun because I can tell others to choose my feed on their aggregator. In attending the RSS Club, I learned how blogs and RSS feeds can be useful for e-learning, especially when professors may not have access to discussion boards in WebCT.

Some cool links I found for getting RSS feeds are:
http://www.gizmodo.com/ (gadget news)
http://news.google.com/nwshp?tab=wn&ned=us&topic=t (sci tech news)
http://news.bbc.co.uk/2/hi/default.stm (bbc news)
http://holographic-universe.blogspot.com/ (and of course, my own blog)
