An idea to differentiate and make some money: Take the questions that have good and well thought out answers and then figure out which products/services the answers pertain to.

Example: What is the best alarm clock?

Keyword them and also figure out which Google Adwords they fit with. Also, create an appropriate affiliate link to the product/services mentioned in the answers. Have a script that buys the appropriate Adwords and creates a link to the product that was chosen to be the 'best'. When people search for "alarm clock" on Google they see an ad for the question/answer/discussion at Fluther, they go there to read about it, then buy it via the link. You earn affiliate commissions. Also, you establish yourselves as the "useful, action oriented answer site". Or whatever.

There are many obvious permutations of this scheme.
