Currently the main venue of public communication for the Reading department is mobile-l, even for completely non-mobile-related mails such as this or this. This makes starting threads difficult (should I write to mobile-l when the topic is desktop-related? Should I spam wikitech-l or wikimedia-l when it probably does not interest everyone?) and fuels the community conviction that the Reading department only cares about mobile. We need a mailing list which can be the default venue of communication.
(Also a #wikimedia-reading IRC channel, but that probably does not require a Phabricator ticket(?).)
