The best way to contact me is via my main email address,

If you want to keep your message secure, and you've figured out the magic incantations needed to use PGP properly, then you can encrypt an email with my key, 1777-5FF3-B42E-401D-511F-22F5-5604-4136-536F-7EF2.

I'm also far too active on Twitter at @yaakov_h, so you can probably grab my attention there.
