I finished it, and felt much the same way. Like eutopia, I'd expect a frank conversation with a superintelligence to be deeply challenging; it would be very surprising if all the substantial advice one had for me turned out identical to what merely mortal soft transhumanists with environmental and social concerns are already saying. In fact, I wonder why the god of the story bothered; he's clearly not telling us anything we don't already know, and he isn't saying it in a way that'll substantially contribute to the meme's spread.

Obviously a human author cannot foresee what "substantial advice" a transhuman intelligence would actually offer; therefore the story's god probably just functions as a mouthpiece for the author. I suggest you stop thinking about whether a superintelligent being would in fact say the things that character does, and start thinking about whether those things make sense on their own terms.
Talking with God is a pleasant and inspiring transhumanist short story. I've got some quibbles, but I'll save them for the comments because I think the story is better without spoilers.
There's a discussion forum at the story's site.
