I have the impression that the vote graphics in the Articles is broken.
E.g. see How to reverese a string in C#/.NET with almost one line of code using P/Invoke[^]. I have initially voted for 3, but this is not shown, even my comment "My vote of 3" is present in the thread. E.g. for this article, there are may more low votes even the graphics shows another picture.
