I'm by no means an authoritative source for this, but "ROS Answers" (ie: this site) is an instance of something called Askbot, which is a platform for "Q&A sites". "Q&A" is short for: Question & Answer, which is the type of interaction we have here on ROS Answers.
So the name would suggest that this is the place to get answers to questions about ROS (ie: "the Answers site for ROS").
I guess it could have been named "ROS Questions", but that might not be a good name from an English language perspective, as it would imply that there are mostly questions here (which may be seen as something negative) while a site that provides answers would seem to be more valuable.
As to the domain name: I believe that follows logically from the "ROS Answers" name: answers.ros.org
.
Note btw: questions.ros.org
does exist. It directly forwards to answers.ros.org
though.
I'm not sure I completely understand the question: are you asking where the
answers.ros.org
domain name came from?Or "ROS Answers" itself?
"ROS Answers"! Oh, i see. Thank you ^_^
