I have several friends, colleagues and family members who read my humble blog. I either tell them about blog additions or they subscribe to the blog feed through Bloglines, My Yahoo! or some other RSS-enabled newsreader. (There are buttons on the right sidebar that let you easily subscribe to this blog.)
I have now added the ability to subscribe to this blog via e-mail. Look again on the right sidebar. Just enter your e-mail address and, once you confirm the subscription, you will receive blog updates by e-mail.
