Seriously, it isn't. I am just testing Disqus ... I hope it works now. I've been trying to get it to work, and I pride myself on a little more savvy than the average user (what with my techie background and all that - so what if it was in a bygone era?) but installing Disqus and getting it to work has been a major challenge.
If this works, you should be able to leave a comment - as a Disqus user, as a Facebook user, as a Twitter user, or with your OpenID, or just plain anonymous, with Name and email address.
Help me test this if you will. Thanks!
