For customer service related to buying e-books, please feel free to write or call — but please do peek at my help page first. My response time for critical customer service questions is mostly within a few hours, a day for less urgent matters.?If your money is involved — payment and order issues, refunds, order issues — my average response time for anything like that is about an hour during normal business hours, or first thing next morning. Most other kinds of questions take a day.

Criticism is welcome. I’ll probably reply if it’s knowledgeable, polite, and significant. If it’s not, I won’t.

Unfortunately I truly just cannot answer most other email. The volume of email I receive would be a challenge for a whole team to keep up with.

Looking to collaborate? I get a lot of cold collaboration proposals, and It’s like talking about marriage on a first date. We just met, buddy—don’t even talk about our second date. We just met! Collaborations are earned, not granted. Pro tip: start with short email. Tag me in an interesting social media post. Etc, repeat. For a long time!

RSS feed
Blog posts “pushed” out to you by the miracle of RSS. Full-text. Members get their own feed.

Extremely active! I share almost everything of interest I’m working. Lots of mostly sane comments.

exTwitter (@painsci)
Yes, still there (sigh) and quite active. Regular content announcements and highlights, science nuggets, and more.

So far in 2024, I’m just as active on Threads as exTwitter. Same posts, no Elon Musk.

Occasional shares of interesting/useful nuggets. A token presence.

I like Bluesky, so I’m there — but my participation is minimal for now.

There’s also a “What’s New?” page that summarizes all fresh content, or sort the big table of contents by date.
