I like that it allows me to have multiple conversations with different people at once, as well as allowing myself personal time management while browsing through these chats! There are some bugs here or there but they do get fixed quickly so don't worry about not seeing them right away - you will eventually see what's going wrong when someone else does too :) It has definitely helped my productivity tremendously by being able of keeping things organized into separate conversation threads which can be closed off later if needed (which saves having open tabs).
