We just posted the results of a skills survey of the Java developers in the 50K JavaBlackBelt Community. Its top finding was the estimate by Java developers that their teams would be 25% more productive if their managers committed to Java skill management.
-- review the full results of the survey
-- receive results of the next/ongoing survey on Java skills in greatest demand
-- discuss Java skills management with others in our blog/community.
... all intended to be useful for you/your organization and perhaps some of which is interesting to a general learning audience.
