[ros-users] Unanswered Questions on answers.ros.org

Instead of hijacking Tully's 2014 Metrics Report thread I've renamed this
thread to comment on David's question :-)

This is just one aspect of the issue, but I see on answers.ros.org there
are a lot of questions about MoveIt!, many of which are unanswered.
Although MoveIt! is a major component of ROS, there is a schism as to where
questions are answered. MoveIt!'s main discussion area is the user mailing
list <https://groups.google.com/forum/#!forum/moveit-users/join>, secondary
is Github issues, but also there are the answers.ros.org questions.
Instructions for how to get MoveIt! support are here
<http://moveit.ros.org/support/>, but I understand why some users are

I imagine there are similar divisions with projects like PCL and Gazebo.
Perhaps we should do something to help users understand the scope of these
various avenues of discussion.
