I have turned off comments on my blog - there was too much spam, and I'm not planning to invest the time to fix that properly.

On the one hand, this is a shame - it removes an opportunity for other people to respond to what I might write.

On the other hand, the idea that this was any kind of two-way conversation was always a badly-maintained illusion. I didn't have any kind of notifications set up to tell me when comments arrived; so I rarely read them, and almost never replied. I don't want to build a commercial enterprise or a "community".

So for the moment, if you want to get in touch, email me. If you want to respond publically, write your own damn blog post. :)
