Will the real Holly and Rivka please stand up?

Site rec: The Institute for Naming Children Humanely. Most fun I've had in a long time. The site even has a list of whether certain names are 'humane' or not. For instance, Chloe is humane but "watch foreigners try to pronounce it" but Chelsea is not, as it means "port and Freudians can take it from there." Or how about Rosanna, which is not a humane name, as it will always be associated with '80s music?

On a positive note, Holly is a humane name - though not if a December baby - but Rivka (sniff!) is not listed anywhere. If anyone knows if Rivka is a humane name or not, please send me an email. Thanks.
