It's interesting, but there is surprisingly little (next to no) details. Are you using map/reduce or Aggregation framework? Is the data out to be consumed by say Ruby client or are you just displaying results on the web? Looks like a pure landing page just to test to see if there is interest. If that's your intention, I don't like baiting HNers instead of just asking. If not, I recommend to put some examples, use cases and more information before posting here.
