Pros

Wonderful culture: humility, empathy and just plain good natured personalities abound. Having worked at many large, high profile internet companies the hardest thing to get used to is .. Yes, these people are also very very smart and talented

Cons

Slack is essentially selling *reliability* as it's main feature, and when it comes to scalability problems, reliability is the least fun (compared to fast, big and kinda reliable i've had at other places) .
