I have switched to Haloscan commenting and trackback for my blog. I am hoping that this will enable non-blogger folks to post comments without inviting too much comment spam. I am looking into whether the previous comments, which presumably reside still at blogspot, can be imported.
I have found the way to get the blogger comments into haloscan. For now, clicking on the permalink of any post will reveal the comments that were left via blogger. Right now they don't count as comments on the front page. I will have to manually cut-and-paste each comment into haloscan. This will be a back-burner project for me.
