Whatever credibility signals you end up packaging for this purpose, it would be great to have a Beta widget that shows those somehow to readers of articles.
I recognize the raw data is out there -- lots of data that could inform credibility is! -- but it's not conveniently cached per page, so for me to look up daily readership, the ORES trust of the latest edit, &c are each separate calls via separate interfaces waiting for separate lag times. I don't want to do that for each article I visit, and even experienced readers in general won't know to.
