My handle is essentially a shortened form of my first name, Gwendolyn. In real life though, I'm mostly just known as Gwen/Gwennie. If someone does call me Gwendolyn, it has a tendency to freak me out a bit, especially if it's from a girl shorter than me (5'7.5"). Recently though, people tell me that they just think the name is pretty and they like saying it, as opposed to people just showing up to razz me.
It's kind of funny, because it's one of those names that pops up in television, but I can count the number of other people I've seen in person with that name on one hand. Maybe it's just in contrast with being in the class with five hundred Tiffanys/Emmas/Codys.
