Hi! I was surprised to see that Twitter is now the preferred method of contacting the Wikimedia Foundation, and that it is much more effective than long disputes and discussions on mailing lists, Bugzilla and wiki pages.
Indeed, it is so effective that it leads to the WMF clearly preferring un-free fonts over their free equivalents; something that, I believe, participants of this very mailing lists agreed /not/ to do.
