This page lists other people whose websites you might be interested in visiting if you found my website useful or interesting. I begin by listing some people I’ve collaborated with closely in the past or have regular current interaction with, and can provide more color on. At the end, I list some others whom I don’t know that well but whose work I’ve found interesting and enlightening.

Issa Rice

Other online projects: Cause Prioritization Wiki

As of February 2015, Issa is a second-year student at the University of Washington, Seattle. He works on the Cause Prioritization Wiki, reads LessWrong, and is very active on Quora.

I first came to know Issa on January 1, 2014, when he contacted Cognito Mentoring, an experimental mentoring service that Jonah Sinick and I had announced on LessWrong on December 28, 2014. We had some email correspondence in the next few months. Starting around August 2014, after Cognito Mentoring had gone in standby mode, I began more one-on-one online interaction with Issa and I played a key role in influencing him to start the Cause Prioritization wiki, which he officially launched in November 2014.

Katja Grace

Blog: Meteuphoric

Other online projects: AI Impacts

Katja is involved with effective altruism and LessWrong. She’s an expert on the anthropic reasoning problem. She’s currently working for MIRI.

My first substantive contact with Katja was in May 2013, when she got in touch with me for a Workflowy on the costs and benefits of open borders and migration liberalization at large. The updated version is here, and you can see a list of similar links on Katja’s site here.

With some assistance from Paul Christiano (mentioned later on this page), Katja began work on the AI Impacts site in 2014 and has been blogging regularly on it in 2015. Although I haven’t played any direct role in the site, I’ve encouraged Katja to work on it and also given her some suggestions.

Sebastian Nickel

Blog: NickelBook

Sebastian Nickel holds degrees in psychology and in mathematics. After making a living as a freelance translator alongside his studies for several years, he is now transitioning into the field of natural language processing. He has also taken up distance studies of computer science at the graduate level.

I first encountered Sebastian in the comments section of a Facebook post by Bryan Caplan. We became Facebook friends on October 26, 2012. Since then, we’ve interacted a lot on Facebook and worked together in many small ways. Sebastian has written blog posts for, and in November 2014, we co-launched the Libertarian Effective Altruists Facebook group. We’ve both learned a lot from each other on how to use Facebook.

Jonah Sinick

Personal website:

Other online projects: Cognito Mentoring (with me)

Jonah did a Ph.D. in mathematics and has recently switched into the programming, machine learning, and data science realms. He has also been involved with effective altruism and has contributed to LessWrong.

I friended Jonah in November 2011 on Facebook after interacting with him on GiveWell’s mailing list. We began interacting more substantively in November 2012, and in December 2013, we decided to try out Cognito Mentoring together. We shifted the project to standby mode in May 2014, due to a failure to obtain enough traction. Working with Jonah was an enjoyable and stimulating experience.
