I don’t entirely agree that more and better documentation removes bugs, problems, questions, concerns, or cuts too much into a 50% drop in site usage. Having documentation is just another tool in the toolbelt, to be used alongside community forums.
Discovery process for myself and many of my coworkers has always been; Look up obscure errors, problems, etc. to get an idea of what I’m dealing with, and then off to the documentation.
If the goal of beehaw is that the user base remain ever small, then by all means jump ship and move on, I can respect that and I wish you all the best. However unless your good faith “rockstars” are planning on building you a platform, you will likely find out that the grass is not always greener on the other side, and that migrations bring additional tensions and work.
