They probably didn't email it because people would then complain of spam. The industry standard is to grab an email address to make only a one-time notification.

All this is irrelevant anyway; Wakemate will get crap no matter if they remain silent, or write blog posts, or send email, or update twitter as long as a physical product is not out in the wild.

I'm actually in support of the Wakemates on this one; I wouldn't have sent out an email either.
