A Case Study in Not Being a Jerk Online
Gary Bernhardt takes a mailing list screed from Linus Torvalds, creator of Linux, and rewords it, making it almost half the length, still as adamant about the technical concerns being presented in the original, but free of the kinds of verbal abuse that plagues the discourse of the open-source community. A really great way of showing how this kind of toxicity in the culture can be avoided without actually hurting your point at all.
