If you want to appeal to people of different languages and cultures, you have to move toward tropes that are universally recognized. Games, references, subtleties that only work in your language are hardly useful.

More and more the writer is aware of an international community of readers for whom dense language use and frequent local references are a hindrance. This seems obvious. I don't decry it or criticize it - it's just a fact.

Any time one seeks to produce for a larger public one inevitably has to drop material that would only be understood by a particular group.

Always read with a pen in your hands, not beside you on the table, but actually in your hand, ready, armed ... Put a question mark by everything you find suspect. Underline anything you really appreciate. Feel free to write 'splendid,' but also, 'I don't believe a word of it.' And even 'bullshit.'
