When a new article is written, wordpress will update the blog RSS and this feed always contains the latest contents of your blog. For this blog, that’s davidtan.org/feeds.
Some people uses feedburner to publish and track where their feeds are viewed, clicked and consumed. Plus, there’s also a setting in feedburner that will sync new posts to your twitter account as well (ex. @davidtanth). You can also subscribe to your blog’s feed in Google Reader to keep track of your own blogs.
