Hi everyone!
It seems that the for-profit company can be as open as the community! I really like the idea of feature poll of the Blue Spice [1] I wonder: have anyone tried to run something similar for MediaWiki? In Semantic MediaWiki we also run polls and surveys from time to time, here is the one: http://semantic-mediawiki.org/wiki/SMW_users_survey_results
I think that such surveys can have surprising results for the developers and they are surely nice steps to openness in MediaWiki production process.
