D’oh
Apparently my pseudonym is the masculine version of the Welsh feminine name “Anwen.”
Oh well. the “wyn” is more appropriate to the Tolkien language I cobbled it out of (from the Rohirrim) and I know of at least two girls named “Bronwyn,” which by those rules is also a masculine name.
But this could help explain why a startlingly large percentage of the bloggers I met in NYC assumed I was a guy until they met me.
