Minor impact if any at all. (Score 1)

IT is a service industry. That being said, it is under no threat from this new technology that provides information.

Compare the situation to the medical field and all you really have is WebMD.com. I don't see any Doctors that were disenfranchised due to patients being more knowledgeable. Sure, it can be argued that there are fewer patients who come in not knowing at all what is wrong, but they are still sitting in the office. I mean really, knowing that your hard drive died due to the heads crashing against the platter just helps you relate the information to your IT personal; it doesn't put them out of a job.

The last point I would like to make is that the availability of information by no means guarantees that people will care to read it. I suppose I could go pick up a "Car Care for Idiots" book to change my oil, but of course I have no interest in that subject and I'll pay to have it done.
