How can we encourage DZone members to answer more questions?

These are some of the things that can be done:

1. When posting questions, make sure to follow the policy. Don't post bug reports as questions, but rather make sure every post to Meta OSQA is indeed a real question.
2. Try to search before posting your question - perhaps someone already asked this?
3. Those with moderator power / enough rep should edit questions to improve their style, tags, and close improper or duplicate questions. When closing as dup, be sure to point to the existing question (current OSQA software doesn't enforce this, unfortunately).
4. I don't know what the reputation levels for OSQA are, but it's possible we don't have enough people with the power to close/edit questions. Until this changes, an administrator can lower the limits to allow more user moderation.
5. Vote and subscribe to questions that interest you - this can help separate the quality questions from the muck.
6. Finally, I believe that this feature will greatly help, if/when it's implemented. Currently there is no easy way to find the interesting unanswered question. I believe that the current definition of "unanswered" is close to useless (at the time of posting the issue, Meta OSQA had 68% unanswered questions). If you agree, vote for the issue!
