Keep in mind that a lot of people who post in these threads use made up online persona that aren't close to who they really are. Sometimes they may use several profiles to support their own opinions in a discussion. Often they are pushing issues that are in the interests of the business in question while pretending to be a pilot. They are usually recognizable by a general hostility and insulting comments toward anyone who disagrees with their agenda but are careful to stay within the forum rules. Tech forums are far worse though. If you speak out against the interests of a large tech company (especially some cable companies) in a public forum expect to be lambasted by fanboys and professional "astroturfers" guarding the interests of their clients.
