Unless we change our mascot to a different animal, I think I'm fine for a while. I picked mine a long time ago when the term Husky Mania was in vogue. I felt it was childish for a while, but now see it as nostalgic.
I'm guessing those who choose handles that are out-of-date prone, might have not been forward thinking at the time. Ones that refer to the number of NCs might want to bump it up a few numbers to give yourself a little more time before you need to change it again.
I wonder if anyone picked up the name Hungry Husky?
