The new ng-conf site doesn't use AngularJS
An ng-conf announcement came via email, expressing this in the 2nd sentence:
"After much blood, sweat, tears, pain and suffering, the new website has been launched, and we think it looks pretty good."
First I thought, that's not too reassuring to read from a web framework organization. So I went to check out the site.
I was surprised there doesn't seem to be any AngularJS used. It looks like Wordpress and JQuery.

It's a premade WordPress theme for conference sites
That makes me think more highly of the conference organizers.
It's a small indicator, at least, that they've got a decent amount of awareness of when using Angular is a good idea, and when it would be overkill.
You can know Angular and its benefits without needing to use it everywhere. There's no point reinventing the wheel writing everything in Angular 2 for a sake of it.
