@Patrick I can appreciate the sentiments expressed by the main developer. If it’s not mature it just isn’t. But I still think the reasons for Whonix having experimental status need to be more clearly presented to (potential) users. What goals have not been met? Get rid of the many nonsense overambitious goals. Define the goals more clearly and not too many.
As I understand this is the main goal and Whonix does this well and reliably. Emphasize the strengths of Whonix as well as its weaknesses. Probably a sensible goal in the midterm would be to just make using Tor browser more secure and private in Whonix than doing so on the host. This is probably what most users do most in Whonix. Looks like it has already been met. 
With many warnings and without an adequate explanation of what Whonix does, doesn’t and should do an impression may be created that it is barely working or not at all. That doesn’t look like the case to me. If using Whonix gives you more security, privacy and anonymity than just using Tor browser (or other Tor software), then users should be made to understand this. Even if Whonix is not prefect. A condition of course also being a sufficient study and understanding of the documentation. Then users will have no doubt about whether switching to Whonix today is recommended and a good idea. Can this question be answered at this time?
@Pano It’s great to see the community has enthusiasm and to hear from you. But I disagree with a lot of what you say about the documentation. There are so many things to consider it’s impossible to make it short and simple. I appreciate every word of it, even if some of it isn’t applicable to my Whonix. Privacy is hard.

I think the Whonix documentation is so rich that it should be of great interest to anyone curious about privacy. They don’t have to be a Whonix user or an aspiring one. Maybe start considering or promoting the wiki also as a standalone knowledge resource. The same may be said of the forum actually, it’s a bit more like a news resource.
Regarding rates of contribution it may be just the way the world is.
It’s not mine, what gives a thread its meaning is that everyone shares 
I didn’t mean extra discussion is bad, better messy than empty.
The below would better fit in the closed Whonix and Tails Discussion
I don’t believe in Tails. The only thing it can do better than Whonix is forget everything locally. But when is that useful? If you’re using your own computer and want control over it, you use full disk encryption. Period. So Tails on your own computer brings nothing of benefit. Using someone else’s computer is firstly a security compromise and secondly a dying habit. Wireless networks are everywhere and most people have a network-capable device with them all the time. They’re getting cheaper, better, more common. Device sharing should therefore decline ever more. It may even become socially unacceptable, not fully without reason, mind my first point. Public computers for general use with unrestricted access are disappearing and the authorities certainly aren’t sorry about everyone being more traceable. They are also out of fashion which matters to the common user and there’s a hygiene problem. So why and when would you use Tails?
