We do 1-1 peer reviews and make changes in real-time so that the developer can see the preferences for code style, naming, indenting, etc.
You should also lead by example. Your post includes numerous spelling and grammatical errors. If you want them to be precise with such things, you yourself must do the same. Sorry, not picking on you, but your developers will follow your lead with any form of writing.
Right, well it's one thing when posting on HN - I'm not really running a spelling and grammar check. That said - my complaints are not around their writing style. Many of them are non-native speakers and I can live with bad grammar & spelling in comments. The pain-point is really the coding style that leads to bugs where they could have easily been avoided.
I do get your general point of leading by example though - and like the idea of "show them whats wrong instead of just telling them by fixing it in real time".
