I added the "Follow by Email" gadget. I find this feature very helpful when I would like to keep up with a blog, podcast, YouTube channel. This way, the follower will get an email notification of new content and not have to keep checking back in.

It is currently at the bottom of the page. I put it there because I thought it might get lost on the right column which is getting crowded. I welcome someone with web design sense to move it to a better location!
