Hi, I want to make some kind of an ongoing quiz on a social network like Gather.

I think of asking a question, that can be commented upon with answers. Rules are, that you have to improve the answer, and yet leave room for another improvement.

Example:
Q: Larger city

Comment 1: Boston
Comment 2: Chicago
Comment 3: New York
Comment 4: Mexico City
Comment 5: Tokyo

Comment 5 looses - it is not possible to improve, since Tokyo is the largest city in the world, no. 4 wins - improving no. 3 and leaving just enough space for no. 5.

Any ideas for questions? Thanks in advance.

I know that my idea will completely twists your former quiz, but I would like to suggest you something.

You could make a kind of "bid" or "ducth auction" like quiz (examples will follow).

[From Larger to Smaller]
Topic: LARGER CITY
Starting point: (submitted by you, must be the Largest city)
Players will submit their own answers, and no one but you can see answers.
Rules to win should be:
1- answer must be unique;
2- answer must be as close as possible (being unique) to the right answer.

Just an idea!

Bye
