Out of curiosity, what's special about Zulip?

The engineering team tested Zulip for a week, and it worked great, especially for async conversations.

Way nicer than email or issue comments for talking things over.

Yeah, I felt looped in on what I need to know, and not distracted by the rest. Awesome for my focus time.

I was out for a couple of days, and it was so easy to catch up, and continue conversations from where they left off.
