It consistently tops the chats of "best places to work". Combine that with the fact that there's literally a movie about how great it is to work there and I'd say that's pretty common sense.
I've found the same thing. Currently I'm involved in 9 different slack channels. Though it's great having more people to chat with, at what point is that just ruining productivity? I'll admit their branding is spot on though. People love their slack. I'm just not a huge fan.
It's an interesting topic since React and the React ecosystem is great but it's so fragmented that it's difficult to get started with. What's the trade off between modularity in tools and productivity?
