Yes, reading the manual is a good first step, but some of our younger members have been raised in a school environment where self-motivation and taking responsibility for themselves is not taught, ending up with people who will take what they consider the easy way, asking somebody.

And, many people have the "I don't need no stinkin manual" view of the world, where lots of the stuff they've put together has a few missing screws and might be a little crooked.
