I agree that this all depends on context.
I’ve always felt that the “Ian and Andrey Show” was basically two guys catching up and we happen to be let in on the conversation. Naturally when two friends talk about stuff they are interested/passionate about there is going to be swearing. (At least there is with me.) And even then it’s not much in my opinion.
But at Microconf when @ian gave his presentation I don’t think he dropped a single F-Bomb, right? I think I would have noticed, because the context was different. And that’s despite the fact that it’s the same audience (literally the same audience for a large proportion of attendees).
I think that so long asa you’re aware of your audience and context and you filter yourself based on that you’re fine.
Now I wonder how self-conscious @ian and @andrey will be about swearing on the next one.
