@JustinHowe I should add, a network of local moms have air quality measurement machines because nobody really trusts the official numbers. Whether they know how to maintain them, I dunno... but their results do seem to match each others' machines pretty consistently.Permalink On twitter.com

@JustinHowe Also, someone who used to work with me knew (tutored, I think) someone working the government office over in Sejong City who, while he never outright dismissed the official numbers, *did* hint that the readings his own machine at home took were consistently worse. *shrug*Permalink On twitter.com

@JustinHowe Which sounds totally conspiracy-theory-ish, I admit. Then again, experience makes me wonder dubiously about how often the devices on the network are calibrated, cleaned, serviced, etc. (And, for that matter, how old they are.) Curious, with no way to check, I guess.On twitter.com
