“Save the world” has icky connotations for me. I also suspect that it’s too vague for there to be much benefit to people announcing that they would like to do so. Better to discuss concrete problems, and then ask who is interested/concerned with those problems and who would like to try to work on them.
I hate to say it, but the icky connotations are sort of the point. I’m interested in people who want to save the world enough to overcome the icky factor.
I realise that “Lonely Dissent” is essentially a troll’s manifesto, and I apologise. But I’m publicly committing to stop writing trollish LW posts.
