One of the issues commented during the workshop yesterday was the difficulty of involving in our projects volunteer contributors that are interested in design.
It is a Q&A site with 15k users and 99% of questions get answers according to their statistics.
I think it is a good way to have some additional feedback from a different point of view, but also to make design enthusiasts aware that they can find design-related projects in MediaWiki.org.
