There's still a perception out there in some circles that chat applications can be a distraction, and I do believe it's important to have a commitment to reel in off-topic threads before they create a cognitive disruption. And it's equally important to be able to give yourself the space to work uninterrupted when you have tasks that require longer periods of concentration. As I write this, for example, I'm using at least two team collaboration tools, but the notifications are silenced so that I can check in periodically as the breaks in my work allow for it, just as I silence social media notifications when I really need to get stuff done.
