I can’t think of an application where a nail is better. Sure, sometimes a nail will do and there’s no need to use a screw, but that doesn’t make the nail better, just cheaper.

Screws genuinely are better fasteners than nails, though…

I have rss feeds that’ll let me know if any of the coins I own spike for some reason.

Ooh, that sounds handy! Mind if I ask where those feeds are coming from?

Technically yes, but in practice any gains are going to be counteracted if not outweighed by the electromagnetic noise from the fan’s motor. To avoid that interference and see any real improvement in your signal strength, you’d have to either use a fan with a shielded motor (the last such model went out of production in 1953, so good luck finding one) or a fan driven by an alternative power source such as a water wheel.

That’s what this meme about ‘sigmaposting’ is poking fun at. The sigma wolf is supposed to be the lone wolf who doesn’t need nor care about anybody else, and for some reason some people look up to that as an ideal to pursue. But wolves are social animals, so in reality the lone wolf is a failing loser.
