Yeah, I tried one out too. I guess they figured the price premium for true frame-based semantic analysis was too high. Unfortunately, it's also the only workable approach. The flame goes here. This is an extremely hot flame.
Hackers also mix letters and numbers more freely than in mainstream usage.
In particular, it is good hackish style to write a digit sequence where you intend the reader to understand the text string that names that number in English. It should also be noted that hackers exhibit much less reluctance to use multiply nested parentheses than is normal in English. This has both good and bad effects. Many introverted hackers who are next to inarticulate in person communicate with considerable fluency over the net, perhaps precisely because they can forget on an unconscious level that they are dealing with people and thus don't feel stressed and anxious as they would face to face. Though it is considered gauche to publicly criticize posters for poor spelling or grammar, the network places a premium on literacy and clarity of expression.
