Vetting the cargo

I remember seeing an extension (for Firefox?) that would shade the background of the text on Wikipedia to indicate how recently a particular bit had been updated.

I thimk the authors were assuming new edits might be wiki vandalism that hasn't been spotted yet, but with known authors, you could invert the logic.

Perhaps a more sophisticated iteration could use colours that somehow represent both age and the authors' demonstrated reliability (based on how many edits they've made / over how long a period / what proportion of them get reverted etc.)

A naïve idea might have the strength of the shading represent age and the hue represent some trust score (amber for newbie, green for OG editor, red for somebody with questionable performance, shades in between accordingly) Obviously, these actual colours would be awful for somebody red/green colour blind, but somebody better informed on such things could suggest a kinder palette:-P
