A Marketing subsite has been added to the Make WordPress network. Sara Rosso — the Director of Marketing at Automattic — made the call for the new channel, and will be one of the moderators. She cited the WordPress Security whitepaper (created early this year) as one of the types of things such a channel could produce, and is asking for interested folks to subscribe and get in touch if you’re interested in contributing.
This is a really good initiative and I’m happy to see something centrally endorsed strictly for marketing WordPress.
