A selection of the design decisions that I question daily:
Why so many channels? Is that the most effective information architecture for trying to help a person stay focused?
Why are there two different places to add people? Why do I need to add you to the team then to the channel in two non-sequential steps?
Why does my teammate not receive the slack invitation as we sit side by side continuously entering his email? Would you care to notify us whats going on?
Why inundate me with every message? Can there be friendlier default notifications?
Finally, why the hell is this thing worth billions of dollars? Best, Nick
