This is missing the point. For you and other developers/very advanced users, the signal to noise ration is definitely decreasing. But didn’t you see the increase in the absolute numbers of technical posts, too?
For a more wide audience who cannot read through pages of code and too technical discussions, who want to know how to “avoid backdoors and hackers”, without knowing what it means (yet), a lower level of discussion is probably helpful – as long as it stays respectful and on topic, of course.
This is why Categories exist. Perhaps we could create Category “General / Trying to understand Qubes” for such and such discussions and “General / With coding skills” for advanced discussions? Developers then could mute the former and subscribe to the latter. There could also be “General / Non-technical” for topics like this or this.
I’ve been also wondering why this is the case. Perhaps, the effect is delayed, because people have been waiting for the new 4.1 version and it will be seen soon…
Sad to hear that. I still think that people do appreciate your hard work.
