If you want to get in touch, it’s always fastest to IM me on Jabber or IRC or to send me a tweet or direct message on Twitter. You can email me at firstname.lastname@example.org, but I’m often slow to reply. If your message is important, it may be useful to gently remind me by other means, or with a followup email.
I think that Pond is much better than email for personal correspondence. You should contact me via IM with OTR to set exchange a secret.
I’m a big fan of iCal formatted event invitations. If you use Google Calendar, you should send calendar invites to email@example.com, not firstname.lastname@example.org.
If you need to send me some kind of physical object, please email or IM me to ask for a mailbox address.
