Universal has established a tumblr page for 47 Ronin. It contains much of what is currently on it’s main site with this exception:
It remains to be seen if Keanu Reeves will actually answer any posted questions but if you are on tumblr you can post your question here. For those not on tumblr who are interested, you can register here.
Update: The link to post questions for Keanu has gone dead even though it is still showing on the 47 Ronin main tumblr page. The period to ask questions is either closed or Universal didn’t think it was such a great idea after all.
