This being a blog targeted to international fans I'll put this remark here.Streaming the auditions is awesome but Nico Nico Douga is hard to sign up for if you can't read Japanese. Yes, there are fanmade guides but not everyone has access to those.Streaming things via Ustream or Youtube Live or putting up a how-to-guide to Nico Nico Douga would certainly be very helpful.
Just register here http://www.niconico.com/ and then you can be logged after into the Japanese version.
^Thank you very much!
