You should be able to get updates on almost any platform now! Simply click on the RSS aggregator icon on the top of the first sidebar, in the address bar, or through your feed reader and wait for updates. Alternatively, you can drop your email in the box up there and click subscribe!
I added comment, email, digg, facebook, and del.icio.us links to the bottom of the fed posts. Not sure if there’s anything else people might find useful, honestly the only share I use is the button in Google Reader. Let me know if there’s a service you really really really want added there and I’ll think about it.
