Open your DMs

Open your DMs.

A random guy on Twitter sent me a DM. He found a bug in Edicek: he couldn't log in. I fixed something that day and thought it was done.

Three months later, another DM. Different person, same problem. And only then did I find out what was actually going on.

Sign-in with Apple worked fine. Sign-in with Google didn't, but only for a small group of people: the ones with a privacy setting that says don't share my first and last name with the app I'm signing into. And my code had a check that said no first name and last name, no registration. It threw an error and never finished.

It had been broken like that for over a year. It worked fine for me and for most people, which makes it one of those bugs that's almost impossible to find on your own. I have no idea how many people I lost because they simply couldn't get into the app.

And the detail that still stings: I was paying for users through Apple App Store ads. Paying real money to bring people to a door that wouldn't open for some of them.

The only reason I found out at all was that my DMs were open. Two different strangers could each reach me in ten seconds. If my messages were closed, that bug would still be quietly burning my ad budget today.

That's why it surprises me when I see founders and brands with their messages set to private. Someone sees your video and thinks "I have a job for this person" or "I want to work with this guy." They tap your profile and they can't write you a thing. Gone.

If you're building anything public, go to your settings right now and switch your messages to open. Anyone should be able to reach you.

You're here to be found, not to hide.
