EA, SSC, rationalist, math. HarryPotter5777 on reddit for contact/stalking, or send me a message (I get email notifications). Say hi if you're in the Twin Cities area! I'm generally happy to meet up with people and talk about interesting things.
If you are in the area and want to meet people who are not me, there is a regular twin cities SSC meetup! Let me know if you want more info about it.
