Blogger has updated their system and now has a commenting system. After some template hacking, I've switched our blog over to their comment system. The upshot is that we lost all the old comments attached to previous posts (sorry) and due to the way they coded the comment system, the posting page ends up showing up in a new window. The good news is that I'm planning on sticking with this system from here on out, and I've enabled "anonymous posting" so that you don't have to register for a Blogger account (although it is free.)
I'm sure it will all go through several changes... but for now, post a comment and see how it works!
