We're a small team of a bit more than 10 people and slack has definitely improved our lifes. Before there was always someone moving around to talk to someone else or internal E-Mails which are equally bad. We use slack sparingly and only have a few channels with many people. Most things happen in private channels. We always "idle-ping" other team members first and do not expect an immediate response. The result is a much calmer office. People move around less and there is less chatter. And we still have the option to use group chat if required. We even added a channel where new commit messages are automatically posted. A wonderful thing to keep informed about what's going on and you can take immediate action if you see something strange. I think this all falls apart if our team size would increase. But I believe for teams with less than 25 people slack is perfectly fine. Above that size notifications probably start to be annoying.
