my hour of writing got lost
Sorry to quibble, but unless you were trying to post three comments, your original comment was not actually lost.
As for the other points... well, I don't think anyone would argue that fixing more bugs faster or writing more and better documentation is a bad idea. However, my experience has been that critical bugs get fixed pretty quickly in most cases. Also, there are some intermediate to advanced tutorials in the rtfm, Bob has a lot more on his site and in his book, and more are being added in the manual and by third parties at a reasonable rate. Keep in mind that Revo is still pretty early in its life cycle compared to other major CMS.
As for using "MODX is for devs" as an excuse, I think if that's done, it's mostly done by us users, not by the MODX team themselves. When I complain about things, which I admit I do from time to time, the core team is always very receptive to criticism and don't make excuses at all.
