No. It's just silly. I like
Jamie for a boy as a nn for
James. Only. Jamee,
Jami, Jaymie, Jaemeaeiey, or whatever--they're just ridiculous, imo, and no matter how you spell it it's still masculine.
Also,
Jaime for a girl also bothers me because I want to say HY-mee (the Hispanic masculine form of
James).
