When navigating the site, you can see linked and related questions at the right hand side:
The number refers to the net score of the question, whereas the color refers to whether an answer has been accepted or not (green if yes, gray if not). Yet, for those questions without accepted answers, it does not tell you whether the question has received any answer at all. This means that if you are looking for answers or if you are looking to answer questions without answers, the current system makes you visit questions which might not have answers or that might have answers, respectively. This is highly inefficient.
I think this system can be improved, by conveying more information (in particular, to indicate whether the question has answers or not).
Is it possible to add this differentiation? One option is to use a third colour (e.g. gray for those with at least one answer, white for those without answer). Another option is to add a second number in the box, like 3/2
or 3-2
or 3(2)
(for a question with 3 upvotes and 2 answers). This can also be useful in questions with accepted answers. There are of course other options (e.g. add an asterisk to those without answers, 3*
).
Benefits
Those who have knowledge on the topic of a question (which is presumably why they are looking at the question in the first place) can get an immediate idea of related questions which have zero answers, increasing the likelihood they might attempt to provide answers. Yes, you can also voluntary search for favourite tags with unanswered questions, but since the essence of the activity in SE is spent looking at questions, the rate of response could rise quite a lot. The same could be said of questions with just one answer, versus one with say three answers.
Those who are looking for answers to an issue might be saved considerable time by entering related/linked questions with answers only, instead of wasting time by selecting (unknowingly) unanswered questions, which they are very likely not going to answer anyway (as they are looking for answers).
