This is not something that comes up a lot, but it does come up occasionally, and it seems time to clarify how you can communicate with me securely, if that's something you're concerned about.
First off, I'm of the opinion that Internet privacy is a fiction. That's why I don't normally use PGP encryption--that, and because normals don't know what to do with it. And frankly, it's a pain in the butt that I'd rather not deal with, as well.
That said, if you have a need to communicate with me securely, the following options are available:
I do have an account on Keybase, which I use primarily on the desktop. I deal with almost all my email on mobile, so this makes it a pain if you send me encrypted email. It's your job to make it easy for me to read what you send, so don't be surprised if I don't respond in a timely fashion. Or at all.
For ProtonMail, it's easiest if you have a ProtonMail account yourself--then the encryption/decryption happens behind the scenes and takes no effort on my part. And it's readable on mobile that way, too.
For WhatsApp and Telegram, you'll need to know my phone number or my username.
To find those out, or for anything else, you can send me an email via my contact form at larry.im/contact.
