+1. This can actually help the entire ROS community.

I usually websearch with a prefix like (site:ros.org OR site:github.com) to reduce/remove false-positives.

With language groups discussions joining the same domain, we can even find some debug discussions only happening in a certain language group (and maybe provide back answers if possible).
