Google+: Is Google's Facebook Killer Doomed to Fail?

Do you have a Facebook profile? How about a Google+ page? Which do you prefer: Facebook or Google+?

You may have both, but not use one as often as the other. You may have just one while waiting for the right time to join the other. The question is: When is the right time? Are you waiting to see which one is the better product? This issue has been the talk of the cybersphere since Google+ was released — will it be the Facebook killer that a number of other social media sites in the past have failed to become?
