If you’ve been seeing 404 errors, I apologize. As near as I can tell, they are related to problems I’ve been having with my .htaccess file for the site. I’ve partially resolved the problem by switching to the default permalink structure, which I am not particularly happy with, but I’m more interested in making sure people can navigate the site when they get here, so I’ll do what I have to do.
I think I have the problem fixed, and new subscription notices should go out with the right link. Accessing from Tweets should also bring you to the right place. Maybe I need to make up a custom 404 page? I’ll consider that. In the meantime, I hope you won’t need it.
