I think we should all drink more coffee.
Joke apart
How about organizing local meetups and collaborate with the attendees to ask new questions and discuss some answers?
I have little traction with professionals around me in Japan, as most people do not see themselves participating in English, but I came up with this idea, so that language is not a barrier. My problem, though, is whose account do we use to post questions and answers? If I manage to take part in such an collaboration, I'll update here with any findings.
Also, Stack Overflow has an incredible momentum, as it is used by professionals forat work. If coffeeCoffee could be used as a main resource for professionals, and event aseven documentation (see the Documentation beta in SO), the momentum should follow.
