Wait… WTF is the “Hay llamas!” thing about?
It’s inspired by an old Monty Python sketch (from the line “¡Cuidado! Hay Llamas!”, which means “Watch out! There are Llamas!”). And I just thought it was very silly and that “Hay Llamas” would make a good username for things. I first used it on the tvChix dating site and thought it would be quirky and funny, but since then I have kind of grown attached to it and decided to use it here on WordPress too, and also on Flickr and Twitter. So there you go.
