• Dyalogues are deeper. They are not real-time, so you’ll have a bit more time to think through your response and write a reply that is well-reasoned and substantial.

• Dyalogues are public. They are meant to be enjoyed by anyone that could be interested in what you have to say on the dyalogue topic.

• Dyalogues are topical. They are an exchange between two people on a specific topic.

IMing is great for informal, private chit-chat; Dyalogues are great for a meaty, publicly-readable discussion.
