If you currently subscribe to this blog via the site-based feed of http://www.digitalheath.com/blog/feed/, that link will still work without any change.
However, if you prefer Feedburner feeds, I am now providing that option (which does provide me with some better reporting options).
On the right sidebar you will see the Subscribe to Homo sarcasmus link (http://feeds.feedburner.com/HeathBuckmaster), and I encourage you to use it :-).
If you prefer to receive email alerts, that option is now available as well, in the box directly beneath the subscription link you can enter an email and you’ll be served.
Best wishes for a wonderful 2008 of insightful and adventurous social media!
