The advent of the Internet and the subsequent tech booms of the '90's and '00's have made information of all kinds-- including up-to-the-minute tech information-- more accessible than ever. Despite its widespread availability, however, not all information available online has been vetted by reliable source such as software companies themselves, and blindly following "crowd-sourced" instructions may lead a user to do further damage to a system.
If you were approached by a user who wanted you to correct a software problem with which you had very little experience, to what degree would you trust a crowd-sourced explanation that you found on a tech forum or other non-official website? How can specialist spot a "bad" solution, even if they have never treated the specific problem they are researching?
