I guess I’m fine with that. It’s at least a place/convention we can encourage and not a topic that needs to be ‘walled off’ into an isolated forum. It hopefully will not have the ros-users problem too - there should be no discouragement from posting to it as discussed above.
My primary issue is in discovering/browsing for them. Tracking and discussing community software releases is such a core activity I would have liked all my devs engaging in. However, the current layout is very category-centric. The landing page displays a category based listing, the top banner does not have a tags drop down like at https://try.discourse.org/. Knowing the tag convention and then searching for a tag is not a process I think many of them would have done without laying it down for them. Shifting what should be one of the most common (or encouraged to be) activities on discourse to a tag based approach when the site is mostly category-centric is a little clunky.
