Contact
The fastest way to reach me is email. I read everything; I reply when something needs more than a one-liner.
What I'd like to hear about
- Corrections, follow-ups, or counter-examples to anything I've written.
- Suggestions for posts you'd find useful.
- Bug reports for this site (broken links, rendering issues).
Response time
I respond out of work hours, so expect a few days. If something is urgent (e.g., a serious error in a post that's actively misleading people), say so in the subject line and I'll prioritise it.
