It's a tough call, theologically speaking. In practical terms, however, people have been and continue to believe in plenty of gods who did not create our Universe. Some examples include the Greek pantheon, modern Wiccan deities, as well as some of the Hindu deities (though this gets tricky with multiple Universes, avatars, etc.). I think that most polytheistic deities are not Universe-creators, but I could be wrong.
I guess if I was hard-pressed to answer your question, I'd say something like, "an agent counts as a god if it is supernatural, self-aware, and possessed of enormous power". But it doesn't really matter what I think; it matters what the believers think -- and not all of them believe that "creator of the Universe" is a necessary property of a god.
The first draft of the 2012 Less Wrong Census/Survey is complete (see 2011 here). I will link it below if you promise not to try to take the survey because it's not done yet and this is just an example!
2012 Less Wrong Census/Survey Draft
I want three things from you.
First, please critique this draft. Tell me if any questions are unclear, misleading, offensive, confusing, or stupid. Tell me if the survey is so unbearably long that you would never possibly take it. Tell me if anything needs to be rephrased.
Second, I am willing to include any question you want in the Super Extra Bonus Questions section, as long as it is not offensive, super-long-and-involved, or really dumb. Please post any questions you want there. Please be specific - not "Ask something about abortion" but give the exact question you want me to ask as well as all answer choices.
Try not to add more than five or so questions per person, unless you're sure yours are really interesting. Please also don't add any questions that aren't very easily sort-able by a computer program like SPSS unless you can commit to sorting the answers yourself.
Third, please suggest a decent, quick, and at least somewhat accurate Internet IQ test I can stick in a new section, Unreasonably Long Bonus Questions.
I will probably post the survey to Main and officially open it for responses sometime early next week.
