I don't understand, why Ask Ubuntu is like this. out of every 10 to 20 questions only 1 is answered. And the Ubuntu website is advertising it as it's main Q&A web site! Don't you think something is wrong?
I really don't want to sound rude, (I'm not trying to be in any way).
First: We only have the information that the question asker gives us to work with. So questions that don't include hardware information, version information and aren't descriptive don't usually get answers. There is very little we can do about that.
The questions on the front page are only questions that have been asked or edited recently, so of course most of the unanswered ones would appear on it. If you search for
isaccepted:yes you will get a list of all accepted/answered questions.
Doing the math from that screenshot, we actually have over 30,000 questions answered here and we're working hard on improving that.
The site, at the time this answer was written, has 90,000 questions give or take.
The answered rate is 75%.
So the inverse is actually true.
1 in 4 questions is unanswered or abandoned. That's quite the opposite of 1 in 20 answered.
