...in business?

Not talking about informed hunches, attained data, or logical thoughts. Just your feelings.

For example, on occasion I notice sites that used to seem full of vitality that now feel quite lackluster. Makes me wonder "what's happening there?" or "are they making any money?" or "anybody there?" when you have no objective reason to state why you feel like this. Do you trust those feelings and do they pan out to be reliable?
