...and now it looks like the problem with the Blog Archive has been fixed.  Looks like I posted one day too soon.  (I waited a week, but I should have waited one more day.)

So, I'm going back to my original blogging style.  Hopefully it stays fixed.  I'll keep my eye on it.  If it ever goes back to displaying "No Title", I'll quietly start putting titles on all my blog posts, but in the future I won't bore you all by making a big announcement of it each time.
