Ask Ubuntu currently has the [lowest Percent Answered of any Stack Exchange site](http://stackexchange.com/sites?view=list#percentanswered).

What do you think about this, and what should be done about it?

Part of the problem is the attitude of questions asked, with little info provided, and often about old or different systems. Also, once answered, the OP does not always bother to mark it as answered.

Apart from that, large amount is probably due to [duplicate] nature of flagging, even if the duplicate question is out of date or irrelevant. This can be a good thing, but considering that most [other sites, with a similar amount of traffic](http://stackexchange.com/sites?view=list#traffic) manage a much higher answering rate, what could be improved upon?


###Update 20140308:

Alright, currently [AskUbuntu is the second lowest](http://stackexchange.com/sites?view=list#percentanswered), due to [this](http://softwarerecs.stackexchange.com/) apparently month old site - but still doing quite badly out of [116 sites](http://stackexchange.com/)...
