Zooko's triangle[1] in action: A BrowserID (like an email address) is memorable and secure, but not decentralized (it's centralized in DNS). A cryptographic key is decentralized and secure, but not memorable. Systems that are memorable and decentralized, but not secure, don't address these use cases at all. (And then there's Namecoin[2], which is a fascinating development, but not likely to see broad adoption in the near future.)
