I'm a moderator on a brand new site, how can I help drive expert users to it?
This will help grow the community as well as improving the content on the site.
I don't think there is a real way to control this as that's like attracting only rich people to your restaurant.
A few things that you can do:
An expert only feels well in the company of other experts. Whether or not a community is populated by experts can usually be told by the standard of the content you find there.
When you see lots of duplicate questions about the typical beginner issues, you know the community consists mostly of total newbies and of some intermediates who believe to be experts because they know the answers to the typical beginner questions. An expert won't waste their precious time on such a community.
To prevent this you need to have a zero-tolerance policy against duplicate threads. When someone opens a topic which was already discussed before, close it and refer them to the previous thread. Even better, create a static page with a FAQ with all the beginner questions and refer them there. That way people will either have to come up with more advanced questions or stop participating.
Another way to ensure a high content standard in your community is to lead by example. Show the community what kind of content you want in your community by starting threads about them yourself. That way you intimidate any newbies and lure in any experts who come along.
