Showing uncalled winning hands - do you do it?

[penisclaw]

Usually when I have a decent hand, and I win without being called, I tend to choose to show my cards. I feel like by showing cards with good hands, people will respect you more when you bluff/smei-bluff bet and it can work to your advantage. I think it could also be a disadvantage though, because when you have a good hand, people will expect you to, and won't call you down and pay you off. Anyone have any thoughts on showing/mucking uncalled hands and its effect on table image? Sorry if this has been posted before, but I couldn't find it in the search.
