Marketing queries & guest posts

The notes I share here are mostly related to research, anecdotes, projects, and other personal things. I’m always happy to hear about something that might be related – that’s part of why I do this! That said, please understand that I will not edit a published post to include a new link unless it is exceptionally relevant. Moreover, I almost certainly will not add it if the link that I receive is a marketing redirect or includes tracking parameters in the URL query string.

Since this is a personal blog, I do not accept guest posts by other authors.


This site has been a WordPress site since March 2015. Previously it was on Tumblr, and in a former life it hid on a subdomain. Until April 2020 it used a colour-heavy theme, and now it uses the WIP Commonplace theme.

This theme is evolving via ongoing conversations with designer friends, particularly Bec Worth and her thoughts on the usefulness of a Commonplace Book on the web. Technically, it borrows heavily from the previous theme used on this site. Most text is set in the variable versions of Source Serif Pro and Source Sans Pro with appropriate fallbacks for Chinese and Japanese characters.

Many thanks to Sam Baldwin, as always, for everything.


If you have any questions about any of the above, or anything else for that matter, please get in touch.
