It is perfect for when you need a longer explanation or question, and you know the meaning/essence will be lost in translation by typing out an email/Slack. It is also awesome for cascading messages to the rest of my team. It TREMENDOUSLY helps interdepartmental communications when "tone" of written information can become a sore spot. Be able to hear someones voice is far superior when dealing communicating with colleagues that have different written communication styles i.e. - brief doesn't mean rude.

I travel a lot for work and often found myself typing long explanations since I wasn't there to articulate it in person. Yac let's me articulate everything verbally

It streamlines our communication by minimizing the need for meetings and long messages.
