That depends. The intention is the same.

I would not call TMavica's post "offensive". Saying that someone's code has some room for improvement when it does is not a personal attack. Would you consider it a personal attack if someone told you that hou are a bad singer?

Schturman is clearly a beginner but he is also clearly keen to improve and, equally importantly, he shares the steps he makes on his way to improvement with the rest of us. For that alone he deserves my full respect and appreciation. No one was born an expert and everyone, even the experts, makes mistakes. The way Schturman shares his experiences for others to learn the same stuff and avoid the same mistakes is nothing but commendable.
