What questions belong on answers.ros and what belong in other places?

I've seen questions related to using ros with gazebo on answers.ros (and even asked a few myself too), but since has become active (and no longer has a wait period for questions to be approved), should all gazebo questions really be sent to that venue?

My personal feeling is that if it's a truly gazebo question then maybe, but if the question involves roslaunch, or how ROS parameters etc are set, then it should be a fair question here, but I'd like to know what the community thinks.

I'm guessing this would also apply to the many other projects that have interfaces with ROS, or using ROS with those projects as well...

This question was asked because I've seen some questions, that I thought were fair game here, sent elsewhere.

I would say, everything that does not pertain to gazebo itself is OK here.

E.g., if you want to know how to construct a roslaunch for gazebo that sets certain parameters in a certain way, you can ask that here, even if they are for gazebo, but if you want to know what parameter to set to make something work in gazebo, ask it at

In other words, if you could replace gazebo by any other package for doing what you want, it is a ROS problem.

The reason for gazebo questions appearing here, might be that either they are old or people just didn't know that there is another spot or didn't remember to ask over there.

On the subject of people not knowing there's another spot for certain questions (like gazebo or opencv), it might be helpful to have prominent links to answers.[gazebosim | opencv | etc].org.

Would this also apply to instructions that are hosted on the ros wiki that include the use of other projects?

That depends on how much the project is tied into ROS. Some are specifically developed with ROS in mind and the authors will regularly check in here (e.g. hector_slam). Others are ROS wrappers for some library - in that case it might be advantageous to look for support at the project.
