The Guardian on a roll this week (and there's one more coming!). Here is an interesting article on internet trolling. Short summary: "When people upset us online, it's too easy to label them trolls. We're all still learning the right ways to act in this space." In other words: apply the principle of charity generously, and be parsimonious with accusations of trolling.
It would be great to see some discussion on this here in comments, but keep it nice! No trolling and no premature trolling accusations, please.
