A number of questions here on meta are geared toward refining the site to get expert-level participation. I think that is a great goal, but I'm not sure it is the right one. Doubly so if it leads to removing a lot of beginner-level questions (though I understand doing that during beta).
The reason that I question the goal is simply that I believe a large portion of the experts we would be targeting will be definably reticent to participate. They already have their group of expert players with whom they discuss the game; I suspect they will be doubtful that much benefit will come to them from participation here. By contrast, by freely sharing insights, they do stand to lose something. Many, like myself and the few that I have invited here, are involved in training sites, and may seek to keep their disclosure of tips to an audience that will pay for the knowledge. (Since my site is small, I am confident that any loss of business would be quickly offset by the added exposure gained through participation here). Others may intentionally wish to keep the field in-the-dark, so to speak to avoid needlessly improving their opponents. Still others may fear that discussing their game openly in public will create a resource for opponents to gain information about them, leading to tougher games against their skilled opponents.
Thus I ask: Are we really targeting the experts? Is that the right move to make?
