Allow me to translate, for those that were lulled into a hypnotic trance by the Patrick Stewart sound alike:
Sunrise A: Additional adult domain cost! Your existing domain strategy just got more expensive to maintain unless you want your SEO to get nuked.
Sunrise B: Brand Blackmail, early period. Otherwise known as "That's a nice non-adult themed brand you have, it would terrible to see something happen to it."
Landrush: Laughing all the way to the bank. 18 days? Try 18 hours.
General Availability: Gone, all the good names are.
