Email is the best way to get in touch with me as a stranger. Please note it may take me a few days to get back to you as I’m often pretty busy.
If you wish to encrypt something to me using GPG, use the ID of A80ACA6F and fingerprint of F24A 9D06 D481 70EC A8CE D0F1 0E93 56AD A80A CA6F.
You can also find me on Twitter, but you won’t find me on Facebook, Google+, Tumblr, WhatsApp, Snapchat, WhateverTheCoolKidsUseToday etc as I have an account on none of these networks. I also have a Linkedin profile explicitly for professional purposes.
