[Opinions] Re: Khaleesi and Katniss
There may be a few kids out there named specifically after current popular book characters (/words... since Khaleesi is a title and not a name), but no more than there ever have been. The world isn't overrun with Arwens and Leias.
I would certainly consider using a name after a book character I loved, but only if it was something that would be easy to live with and blend in well. Like Arya would be one. Not that I'd use, that I think would be easy to live with. Arya the character annoys me too much.
