Haloscan commenting and trackback have been added to this blog. Why a second time? Because I messed up the html after the first time. Rather than try to figure it out, I went back to Haloscan and used their robot to reinstall the commenting and trackback code. I also disabled the Blogger commenting link, since there obviously is no reason to have two comment services. I prefer the Haloscan comments to the Blogger comments. It seems to work faster, and is cleaner. I switched from the Haloscan system to Blogger's internal comment system when Blogger added it. The first comment system I used came from a company that went belly-up, and I was afraid the same would happen with Haloscan. But enough techno-minutiea.
