Re: Chat Box, Shout Box and Comment Box. Need enlightenment.
It's perfectly okay if the commenting user's own page refreshes when the comment is submitted. It is not okay if everybody's page refreshes every few seconds to view the comments other people have posted. When that happens, it's a "shoutbox". When multiple independent conversations can be initiated in that fashion (either user-to-user or in groups or "rooms") it's a "chatbox".
