Matrix:
@mm-
:matrix.org Matrix is probably the best way to contact me for real-time communication.
It supports end-to-end encryption and lets you send text messages, photos, files, and group messages as well as video chat.There are many Matrix clients for Android, iOS, and desktop. If you’re new to Matrix, I recommend checking out Element.

Email:

@cns.nyu.edu Note: My response time can be fairly slow, and I may forget to reply. I only check this email when I’m on my computer, I cannot check it through my phone.
You can encrypt messages to my PGP/GnuPG key, though nobody ever really does.

Phone/
Signal: +1 (650) 887-5788 Feel free to call this number. I’m fine getting phone calls*. I even made this number easy to remember: the local part of the number (8875788) is a palindrome.
If you want to send text messages, photos, or video chat, you can also use this number to contact me via Signal, an end-to-end encrypted messaging service.
SMS messages are discouraged. Even though I can receive SMS messages on this number, it’ll usually be a few hours before I see it, and for technical reasons my ability to reply via SMS is limited.
Note that I can’t receive MMS (i.e., photos or group messages) on this number at all. Use Signal if you want to send me a photo or group message, or better yet, use Matrix.
* Unless you’re a telemarketer.

Phone (toll‑free): +1 (844) JOSHUA-M
Yes, calling me on this number actually works (most of the time). However, only phone calls work. I can’t receive or send SMS or MMS messages on this number at all.
Calling this number from a payphone does not work. It used to, but payphone surcharges increased to 50¢, then $1.00, and eventually my provider stopped accepting payphone calls completely. ¯\_(ツ)_/¯
There are some ways you should not contact me, mostly because I no longer check them.

Facebook
I might go years without checking it. A friend once asked for travel recommendations to Shanghai and I didn’t see it until two years later.

WeChat
My Chinese phone is old, slow, and usually turned off. Unfortunately, messages that don’t get delivered for a few months can get dropped completely, meaning I may not see messages at all.

AIM
Hahaha. No one’s asked, and I don’t think anybody I know used it by the time I graduated high school. I don’t have Pidgin installed anymore either.

Yahoo Messenger
Yahoo deleted my emails after I forgot to log in for a year. Yahoo also deleted my (and everyone’s) GeoCities. :-(
