The main reason for this, in my opinion, is that people usually look for the easiest route for answers. Googling, or posting on forums is the easiest by far to do.

Although, there are many better alternatives, like help programs. People just are reluctant to use them due to their negative experiences with Windows help (a common example from the Windows website is to use the install disk as a recovery tool. People aren't very warmed up to that.).

If we somehow get more active Maemo Greeters around here than trolls or haters, I think we've (for the most part) solved the problem here.
