You can subscribe to this blog's RSS feed by using Firefox's Live Bookmarks feature. Then all new posts will be "pushed" to your browser. Here's how to do it:
1. In Firefox choose Bookmarks > Organize Bookmarks, and create a "Feeds" folder on the bookmarks toolbar.
2. Open this blog in Firefox, scroll to the bottom and click on "Subscribe to: Posts (Atom)". A new page will open in the browser: select Live Bookmarks in the drop-down list, and click Subscribe Now. Add the bookmark to your Feeds folder. Presto!
The drawback to using Live Bookmarks is that the bookmarks exist only on the computer you used to subscribe. An alternative is to use a hosted feed reader such as Google Reader. Then your feeds are stored in the "cloud" and may be accessed from any machine by logging in to your Google account.
