But that doesn't tell me how Bloom filters work. I don't care about his dinner or what favors he owes, unless he's planning on turning those expository details into a clever metaphor later in the article, or if they really are something that's important for me to understand. I'm all for educational pieces that are told through a conversation between characters - you can get some creative writing out of that. However, the bug that he's asked to fix, the Polish typographer friend, and the dinner scene are barely connected to the subject. We don't even get a nice technical explanation of why the bug is impossible to fix or what that means with regards to the trade-offs in using Bloom filters.
