I like that it's an easy way for our team of 15+ people (technical & non-tech) who work remotely all over the world to communicate with each other without having them have to go through so many different channels/apps! Their interface could be more user friendly - not everyone will know how use something they've never used before.
The only thing we dislike about scoool right now is their pricing model which makes things expensive compared to some similar services out there such as Slack or HipChat but overall this has been very helpful in keeping us connected when working from home during COVID times. We're able to easily share links between teams within our organization while also being able to keep up to date via real time chat messages / text messaging features etc.
