In trying to save disk space on my webhost, and in knowing now what caused it to break before, I've gone to dynamic archives on my blog.
In the process, I've changed my file name extension for my blog entries. Old entries referenced .shtml. New ones are just .html.
So yes, I've broken all your old links to my blog. Again.
It may happen again in the future.
Fortunately, it would be an easy enough fix if you cared enough about my links to just look for anything that was my blog and changed the reference from .shtml to .html. But that would likely be a lot of work.
I'll see what I can do about an error page or redirect.
