It may have been short-lived, but it has a HUGE and very devoted fanbase. If you use it, be prepared for lots of people to ask you if you're a fan for a very long time.

If you name your kid
Hermione, you're going to be asked if you like
Harry Potter. If you name your kid
Serenity, you're going to be asked if you like Firefly.
