This looks really cool. Does it have cross-origin resource sharing enabled? This would be useful for sites that would like to use it directly from javascript.
EDIT: I've just seen the login mechanism; I don't think CORS would be useful with this.
Sure, you would need to login for most endpoints, but I have a number of additions that I'm planning: OAuth, HTTP Basic Auth, and JSONP when given a callback parameter.
I agree, it'd be useful to use some of this data from JavaScript, but only a couple endpoints are publicly accessible (statistics and feed info, really). Everything else depends on the user's subscriptions and intelligence classifiers.
