You know those automated services you see on them poorly created websites you too often stumble across? Why do they exist? What is the point of a robot answering your questions? They very rarely understand the problem you are having or the question you are asking. When they do understand, they often just give you the office times so you can call up and talk to a human being. What is the point of these robots? I for one instantly close them when they appear and I would be hugely surprised if anybody actually sits there and attempts to converse with them.
These robots are just a waste of resources. If you are producing or managing a website – do not waste your time installing an automated response robot!
