I've noticed a few Survey type questions, which rely on feedback entries from the community which then get voted up or down. Unfortunately, there is no way to prevent duplicate entries, or easily identify them and merge them, or restrict entries to a single answer.
This results in the same entry getting split votes.
e.g.
- stackoverflow.com/questions/130095/most-useful-free-java-libraries
- stackoverflow.com/questions/529757/are-there-any-famous-one-man-army-programmers
This made me think of categorising the question types, similar to BlackBeltFactory.
There when the question is being composed, the author selects the answer type:
- Multiple Choice
- Free Text
- etc.
It would be nice to be able to mark a question as "Extensible Survey", and identify unique answers based on a keyword, and allow merging of similar answers with the resuly being summed.
