Alright, if you have a feed reader, I just put up an Atom feed. Go to the bottom of my page and click the subscribe button! Then you'll be able to see ~ the first paragraph of a post, but you just click the link to go to my site and read the whole thing.
If you don't know what I just said, let me explain. A feed reader is a program (like Google Reader) that searches (multiple) webpages and lets you know which ones are updated. Pretty much, you can check a program that checks multiple sources and lets you know which ones are updated. This beats surfing to my page and just checking if it's updated or not. I don't know a whole lot else about it, but I just had my last midterm of the semester today and decided to goof around online.
I've already subscribed to a couple blogs, including my own. Hopefully that way I'll be able to see if it's doing what I think it should.
I'm not sure what the advantages/disadvantages are to using Atom vs. RSS. I don't know if it's possible to output feeds in both formats for the same blog or not. If you know anything and have a suggestion, let me know.
