4) Besides being bad etiquette, this is also downright against the rules of most poker rooms. You are NOT allowed to try and influenze the action in hands, you dont participate in, or to collude with other players by giving them advice or information about dead cards.

In any other situation, sure, do your best to keep the game flowing. This is in everyones interest including your own.
