I would have preferred an in-depth examination of a few examples, rather than a very brief look at a single part of a dense infographic. Errors are not forgivable, but there's a difference between a single error on a sheet that contains three dozen facts which are sourced and many deliberate distortions on a sheet with a few facts, none of which are sourced.

I'd agree that many infographics are just awful at conveying information; people aren't trained in stats to create or read these graphics.
