Lgtm, on hold for merge until we get a data measurement plan confirmation.

@dbrant Can we remove the hold? 🙌

Getting ready to merge but was curious about one thing:

It works very well for en, but for other wikis I feel like the main page parsing or the page title parsing is not working so well.. for eg: Today's hi featured article is glacier national park but widget is showing canada Guessing this will need to be worked on as part of our actual widget update work and not an issue for this pr?

@sharvaniharan Yep, let's merge and iterate on the finer details as we go.
