I haven't had much interest in the whole 23andMe trend. I'm very secure in my identity as a young Caucasian woman from the suburbs (now trying to make it in The Big City! *cue cheesy sitcom opening*) and am not sure what the takeaways are supposed to be. My family's been in the States for generations and we're far removed from our origins as Italian-speaking seamstresses/appliance salesmen/fearful Catholics. Even if the test turned up something I wasn't expecting - like 2% Native American heritage or whatever - it wouldn't change my understanding of who I am, or how I came to be. Others enthusiastically research their ancestry through genealogical websites and DNA tests, which I assume gets them in deeper touch with their roots.
