If you want to know what people think, ask broad questions and listen to the answers. Asking questions like this where you specifically exclude some points of view means you'll get "data" that statistically worthless.
Well, even more worthless than the usual polls on HN.
I'm sure lots of people on HN are all very excited about Google+. Fine, I'm happy for them. Really. It's just that they're currently like puppies, pissing about all over the place. I'm doing my best to ignore it all, but it's not easy.
But I'll do what some people clearly want and go away now.
"I'm sick of the hype already and I can't be bothered to try it."
That actually excludes more options than it adds. It is an explanation with unnecessary complexity. Applying Occam's razor would turn the option into "I have not tried it," which is indeed a missing poll option.
