Well, if there is demand, I can assure you that I can give monthly updates about the progress of 0 A.D. with the same quality and factuality of the first post of this topic.
I think he would only do that when Alpha 24 is released, since the majority of his fans don't use svn and only use the current alpha. Anyway one can just install Alpha 23b and play it, if I understand correctly, you can have both the svn version and alpha 23b installed at the same time.
What would be actually nice is to merge back Atlas with the game. I believe that to do so, we only need two more features in the GUI, scrollbars, and colorpickers. We discussed it with @bb_ and @Imarok at FOSDEM.
