That's a lot of work and as a developer I couldn't care less, since it's just a side project. Just ask people about your core message and if it doesn't resonate, change things.

This is the hardest thing to get right. Too much instruction will be counter productive, too little will be unpredictable. Black magic.

I'd instantly unsubsribe. Leave me the alone please with your followup mails. I can instantly tell if your personal touch email is sent 60 min later that it's a bot. Product hunt follow up mails on my submissions are bots. I find it lame.

What you listed above already takes a fulltime job of 1-2 people.
