This site has always been a one-way street. I write, and you happen to wander by.
As of this week there's a mailbox at the end of the lane. If you'd like new notes to land in your inbox, there's a quiet little form at the bottom of every note, or right at markheinz.com/subscribe. Now and then, not every Tuesday at nine. Once in a while I'll send something that never makes the site at all. No noise, no tracking, and one click gets you back out.

Flag up.
I built it on my own rails, same story as the last note.
And if you're reading this in your inbox already: you're the reason it exists. Hit reply anytime. It lands in my real inbox, and I read everything.
