I wanted to explore the concept of recursion when applied to a conversation. Each comment is treated as its own forum, creating the opportunity for discussion detached from the context in which that comment was created. The idea is to see how quickly people can go off-topic.
Every node in the tree is structurally identical to the root, so the same UI and the same data model handle infinite depth without any special cases. It is more of a thought experiment than a product, but it was a fun excuse to build something where the parent and the child are the same shape all the way down.
