Haloscan commenting and trackback have been added to this blog.
Update: This was an experiment I didn't like the results of. I may try again later when I can devote more time to it.
Update: I've added inbound Trackback capability using Haloscan. I had Haloscan commenting enabled briefly but turned it right back off after deciding I like the way Blogger does it just as well. -- Contrary to the impression you might get at http://www.haloscan.com/, the free version of Haloscan does not include email notification when you get a comment or a trackback. I may end up removing the trackback code also for that reason but I'll try if for now and see what I think of it.
