I already had a google ID. Signing up to Hangout asked for Google+ registration, forces to set the public name of the base account and forces activation of Picasa. I actually bailed out of each of these steps once, just to check that it won't sign up without all of these. Comparing it to skype, I actually have two skype accounts, one "public" for friends and work related things, and set on my workstation, and an obscure private one that only a few family members see, set on y phone. Having the same set up for Hangout would feel like a nightmare with all the related services entangled, switching signups even to look at pictures etc.
