Use "care" with care.

I'm an employee of the Centre for Effective Altruism, but my thoughts are not necessarily those of my employer. As someone who frequents the EA community in the Bay Area, there's a verbal habit that I've heard a lot and of which I think we should be wary. In discussing what... Read More
