It isn't always as easy to teach a newecomer. I myself have tried to explain how WA works to a couple of beginners, but unfortunately the reward of doing so is zero. Why? Because I never see them come back to the gamr anymore.
Not everyone communicates in English and that only might be one of the reason they lose interest.
Some players just comes to WA to re-experience what they once had as a child.
Old schoolers usually neglect the presence of newcomers. A lot of experienced player alias and troll beginners. That's my Impression of it.
People are more selective of who they mingle with, if you are not talented and build your way up to the food chain, you are pretty much on your own until you reach a certain height to be noticed by the nearest beacon.
