Nice work on the API!
I wrote a basic consumer of this API at http://codepen.io/Krinkle/full/wKOMMN#wikimdia-pageviews
Cool! Check out dv.wikipedia.org though, some of the RTL is messing with your (N views) parens.
The only hurdle I found is that the 'articles' property is itself
nested/double encoded JSON, instead of a plain object. This was somewhat unexpected and makes the API harder to use.
Right, for sure. The data had to be stuffed that way to save space in Cassandra. So we could parse it and reshape the response in RESTBase, and that seems like a good idea and probably wouldn't hurt performance too much. Do you think it's worth the breaking change to the format? I'll post on the bug that MZ filed.
