One point to note here is that if you *do* return JSON to a browser, and 
you give it the MIME media type 'application/json', that even if the 
user *wants* to see the JSON in her browser, she may be disappointed. 
Last time I looked, I was prompted to download things of that type, 
rather than 'seeing' them in my browser.

Servers might wish to consider that when performing content negotiation 
with a user-agent.
