Rss Feed

So I thought I had set up an rss feed before but I had not. Here are the two places you can get a site feed for my blog:

http://www.garciapoet.com/atom.xml
or
http://feeds.feedburner.com/EdwardGarciasBlog

I'm really not sure of the difference as I have shamefully not kept up with Rss or podcasting technology. Let me know if I need to set up some other kind of feed if you can't use these two. Also let me know if its redundant to have these two set up for as I told you I'm dumb about rss.
