Can any Q&A site stand the test of time by only offering Q&A (serious answers only please)?

Anyone who’s been a member of a social networking site of any sort, knows the field is completely over-saturated. Most of you came here from other sites. Those of you that have, know how often Q&A sites fail or deteriorate.

From a business perspective, a successful business needs to bring a unique commodity. Now I know immediately people are going to say “Fluther’s users are unique, because no other site has these people”. So does every other social site. Every site is going to have their standouts as far as members but users on these sites don’t differ that much from a business perspective.

Q&A is all over the place. What additional services could a Q&A site offer users that would make it a standout amongst others in the industry?
