I added a subscribe option in the sidebar to the right using a tool created by Feedblitz. I've never used Feedblitz before, so I'll be curious to see how this works.
Update 10/11/06: Here's an example of the email you would get if you subscribed to this blog via Feedblitz. The email would contain a few sentences from each new post, and you could choose to click through to my blog to read the rest of the blog entry. Looks pretty harmless to me.
