Monday is a special day. Firstly, it's the fifth anniversary of Second Life -- though not the birthday, a fact which Linden Lab kind of drummed into me in 2006, when I made that mistake myself; The birthday is in March, the Lab insisted at the time, though the anniversary is in June.
The Lab seems to be changing that tune and calling June the birthday nowadays. We're not sure if that's a concession to popular misuse, or if the Lab has become genuinely confused over it. It doesn't really matter, though. Monday's a special day for more than just that.
Monday's the first day after the 90 day grace period on trademark use has expired.
