Ask HN: What conference do you wish existed?

I left my job several months ago because I needed some time away from programming to recharge. Hosting a technical conference will allow me to both keep in touch with and give back to the community while I'm effectively on sabbatical.

What does the conference that you’d most like to attend look like? I’m interested in everything that comes to mind, from people you want to hear speak or topics you want to see covered, to more mundane things like scheduling or format preferences.
