One of my favorite features of HN is that it lets you limit how much time you spend on it per day. I love systems that work with the users' interests in mind, and I think that this coworking chat does so more than almost any other chat app, because it has clear work periods where people can be productive.
Somewhat related: I think VR is going to be huge for coworking. If you've used BigScreen (http://store.steampowered.com/app/457550/) you'll know what I'm talking about. While you can't see peoples faces yet, and resolution in VR is still low, it really does feel like you're working right next to somebody, and I could see it be a thing.
It's an interesting question of whether it might make sense for me to get into that space with Complice (which is mostly a productivity app—the rooms are just one feature). I can see reasons why that might make sense but I think it's ultimately pretty far from my central value proposition and it would make more sense to partner with BigScreen or something instead.
A nice excuse to try out pomodoros again, too.
Here's the thread I saw:
It's easy to add a few new people to some who already know each other, but harder to just throw a bunch of strangers (some of whom are more in troll-mode) into a room together.
