Dear Hacker: Stop signing up at Google, Facebook, Yahoo, Twitter and all the other personal data collection services, if you care about your privacy. I'm living a happy life without such accounts, and so can you.
My clearly stated preference was to not link my pseudonymous identities on G+ and YouTube, as well as not to link either to real-world identifiers. I'd actually posted on the custom URL issue (phone number required) a few weeks back. That identifier then turned out to show up as a reverse-lookup to your G+ account. There are people who know me IRL and have my phone number. I'd prefer they did not identify it with my G+ identity.
