very simple

This blog is not a public forum. It is my personal fiefdom.

With the exponential increase in spam commenters and registrations from spambots looking to exploit loopholes, I have eliminated comments (for the six people who actually ever left legitimate comments anyway), and turned off your ability to register. From now on, if you want to tell me something, or more generally comment on one of my posts, you will either have to contact me using the contact form (link available at the bottom of the page) or use one of the “share this” buttons I have added to the posts.

As a side benefit, this will also help me reduce the amount of personal information this website gathers about you, so that my GDPR-mandated privacy policy can get a heck of a lot shorter.
