Since I have not yet been able to devote time to finding an HTML widget to show 'most recent' posts in previous comment threads, I'm forced to do it manually (and if any of you know how to add this feature to blogger, please, post it in the comments under this thread, thanks).
Update: OK, for those of you using Blogspot, face Eric's house and bow. He has provided the answer. You may add a rudimentary most recent comments widget using the following procedure:
Step 1: Go to Customize.
Step 2: Add a page element
Step 3: Select 'Feed'
Step 4: enter the following: "http://.../feeds/comments/default" (replace ... with your url and leave off the quote marks)
Step 5: refrain from speaking poorly about lawyers for at least 24 hours (you can do it, unless you're a, you know, lawyer).
An example of this widget has been added to Stonekettle Station, over there ->
Yes, over there -> scroll down until you find it.
Michelle K. and I have been continuing the discussion under the Cloning post.
As Steve Buchheit pointed out, my original post contained a large bit of rather crappy science. I thought about going back and fixing it, and decided instead to let it stand as written. As I've said elsewhere, yeah, sometimes I'm a bit off-base when I get outside my area of expertise, and this was the case with the original cloning post. However, I'm learning things, which is always first and foremost the point of this blog, because really it's all about me. And I'm finding the discussion with Michelle fascinating and the rest of you might too. As I suspected when Michelle joined our little group, she's a worthy addition, especially since her view points are, to some extent, the polar opposite of my own - though I do think we have more common ground than not. Again, I find her comments interesting and thoughtful and you might too.
