Author of the linked post here. I've actually done more Go than Chess in the past 6 months - I enjoy it a lot. My dream is to find a game that captures what I love about both Go and Chess. I've seen many examples of how not to make that game, but my mind turns back to that question every now and then.
The lack of rules while opening up the world of complexity is what makes go interesting. Since chess involves 'functional pieces' I feel it may be doomed from the start. The two games may be scratching entirely different itches I'm afraid.
