I'm trying out Disqus comments, since the lack of subthreading in typical Blogger comments strikes me as an obstacle to the potential for good conversation.
It would appear that no one's avatar from the old comments I imported survived unscathed--including even my own. Instead, all of us have had our avatars in the pre-Disqus transition comments replaced by the "default" avatar I selected for commenters without Disqus accounts. Sorry about that. I hope for those of you already using Disqus accounts that the system will recognize them going forward.
(In case you're interested: that default image is of a scribe I imagine to be writing marginalia of his own, and in keeping with the "Christ Enthroned from the Book of Kells" background theme of the desktop version of this blog, the image is taken from a manuscript of Giraldus Cambrensis' Topographia Hibernica.)
If you do happen to comment here or on any other post, I'd be grateful to know if the Disqus system is causing any aggravation. If it's a pain, I'll scrap it. Thanks.
