The US has a serious problem with saying normal things like fuck, cunt and shit. I find it extremely offensive to hear beeps in series and even the verge author self censors his article. Fucking stop being hypocrites.
Twitter seems to filter through the prism of US standards of speech. Woe betide you if you're Scottish and use the word cunt. In Scotland there's quite a lot of nuance in the usage of cunt. In fact I go so far as to say that the use of "profane" language is a bit of an art form in Scotland, but sadly not appreciated by our Facebook and Twitter overlords. https://www.youtube.com/watch?v=qdCmFg4xIPI
Obviously context and tone play a lot into it and both "cunt" and "mate" can be friendly or threatening/derogatory depending on delivery and circumstance, but I imagine it would be remarkably difficult for people who aren't immersed into Australian culture to figure out which is which based on text alone
