I don't know what's going on, but there seems to be an issue with the Haloscan comment function. Poor LibertyBob left a comment on my last post hours ago and I didn't find out about it until Howard kindly let me know that he was unable to leave a comment at all!
After a few reloads, I'm able to see them, but you may have difficulty. If so, I apologize and appreciate your effort.
Update: The problem seems to have been resolved. If anyone else is having the same problem, however, you can log in to Haloscan and force the comments links to update through the settings page. A lot of people were having trouble earlier.
