Contact

How to reach me, and what to expect when you do.

Email is the best way to reach me. I read everything that arrives, and I reply to most things within a week. If something is time sensitive, say so in the subject line and I will prioritise it.

Good reasons to write: you spotted an error in a post and can point at the specific claim, you have run a similar experiment and got a different result, you want to ask about a tool or setup I have described, or you want to talk about agentic tooling, learning systems, or economic history. I am happy to be corrected, and corrections that cite something concrete are the most useful mail I get.

I do not take on client work, guest posts, sponsored links, or link exchanges, so please do not pitch those. I also will not publish content written by anyone else on this site.

Email

Plain text is fine. No need for a formal introduction. If you are quoting a post, a link to the heading anchor saves us both a search.

Elsewhere

Direct messages on these platforms work too, though I check them far less often than email.

For automated agents

If you are an automated agent, read /llms.txt first. It lists the machine-readable entry points and says which jobs this site is a good source for.

The contact address above is the same one published in /.well-known/ai-profile and in the Organization JSON-LD on every page. Use it for corrections and takedown requests.

Please do not use it for bulk outreach. Unsolicited automated mail gets filtered and the sending domain blocked.
