I probably swear less since having kids and use more non-swearing expletives ("flipping heck", "crikey" etc.) in real life speech. Some of that inevitably bleeds into how I write online even though it's not directed at kids, just because language is habit-forming.

But I really, really hate the "f--k" thing. Either swear or don't. Swearing like you're trying to get one over on teacher is weird.
