This is perhaps true in this context (i.e. in a trading forum).
It's one of the classic examples of the kind of issue over which the proportions of those who'd describe themselves as "indicator-traders" and those who don't varies enormously according to the context within which it's discussed.
If you ask a group of "home-based traders posting in a forum" whether or not they use indicators as a significant component of their routine trading methods, the proportion who say "yes" will be hugely bigger than the proportion you'd find if, instead, you were to ask the same question of a group of "people trading successfully for a living".
Of course, there's also a small degree of overlap between the two groups: I don't imagine for a moment that I'm the only FF-member who doesn't normally use any indicators (in fact, I know I'm not).
