The link to the
Nyan Cat video subscriptions page on stackexchange.com on the newsletter preview is broken because the account was deleted.
I suggest that this link will be replaced by a
newer older video, maybe this one?
This great injustice has been fixed.
I'm also happy to report that this is the first commit to any of the Stack Exchange repositories in 2014, I couldn't have asked for a better bug to set the mood for the year, thanks!
