I've observed, on many communities, that sometimes a member (or group of members) never seems to be satisfied. Whenever a change is made by the administration, or a new feature is added, or something is removed, etc., the member always finds something to complain about -- whether it's legitimate or not -- and seems to enjoy expressing anger. The weird thing is is that these members seem to stick around: they still post throughout the forums and spend a lot of time within the community... but they always find something to be dissatisfied with. What do you think is the reason that some members do this? How do you handle these members on your forums? And how do you react to them when you encounter them on other forums (not your own)?
