Dont worry, it is still not dead. There are few people actively working on it. Scott and pupi1985 recently added some nice features, you can see on Github. I'm also coming up with new q2a site(with latest Github version) just for testing and features discussion purpose. I will launch ASAP.
If this script is so important for you then I feel you should be part of q2a team, that will help to improve. http://question2answer.org/qa/56130/q2a-testing-team-anyone-interested-to-join
If you are looking for some plugins then check http://question2answer.info
. there will be verified plugins section on this site very soon.
Hope this info changes your mind to switch away from Q2A :)
