And it makes me wonder about using similar approaches to break down the echo chambers we find ourselves in. We have a perception of what's normal based on what we see, but what we see is based on what we're already exposed to and what we ourselves do. Randomly seeing what a bunch of other people did this week? Great for that.
I also saw someone rave about "Donut" this week - schedules random 1-on-1's with people in your company to help with cross-pollination and bigger picture context. Chat Roulette and what a dumpster fire that is comes to mind, but I wonder if a LinkedIn-based service of a similar nature would be good just to learn about other companies, other corporate cultures, etc..
