I don't see Jig as a Q&A site because needs, unlike questions, tend to be personal in nature and change (or even die out) over time. The same need could be posted by multiple people in different locations, or by the same person over time, and all could get different answers.
With that said, Jig will have to fight the only known certainty of any online community: as your user base grows, your quality declines. I can already notice the difference in both the needs and the answers posted now from those of just few weeks ago. Let's hope the Jig team has a strategy in mind to keep the trolls at the gates.
In any case, great job!
