To all readers:
Sorry, this blog has been "spammed to death" with literally thousands of unwanted and inappropriate "comments." We are now in the process of cleaning it up.
I have temporarily turned off commenting, but would prefer to find a way to filter comments to remove the spam. (Advice on how to do this is welcome.) If we can't do this appropriately in Movable Type (and still allow commenting), we will move to a different software.
My apologies. Once this is cleaned up I will begin posting regularly again.
