What does the reply button do?

Like JS-Kit, Hoocoodanode supports threading, primarily to make it easier to see who is responding to whom. When you click on reply, your message is associated with the one you reply to.

When someone is viewing a response written in this way, a link to the original comment will appear at the top of the reply. This helps make it easier to understand people saying '+1!' or 'Word!' for no apparent reason.
