As my name is
Katie, I feel like I might offer a different view on this name!
It isn't my given name and I like it that way.
Katie is a nickname for
Katerina. I think just being
Katie alone would be weird, as I don't think it has enough substance to hold its own. Another perk is that though it is my name, I do love when I'm called
Kate, as it feels more sophisticated/less childish. I do think it's cute and not a bad name by any means; it's simple to pronounce, (most) people can spell it with no problem, and I haven't met
that many
Katie's meaning there isn't usually a time where I had to be
Katie C.
I think it's a great nickname to be used with many names, usually
Katherine, but I love
Katerina as mine, and I wouldn't use it as a stand alone first name.
