The difference is not that big (154/​125=1.232), so it could be unrelated to the quality or format, and instead have to do with timing or other things.
One big difference is the inclusion of several examples in the post itself here, and credit for that should go to the authors, whereas users may give most of the credit for the examples in your question to the corresponding answers, not the question itself. If someone wanted to upvote specific examples in this post, they’d upvote this entire post, whereas for the question, they could upvote specific answers instead (or too). If you include karma from the question itself and the answers, there’s far more in your question, although probably substantial double counting from users upvoting the post and answers.
