I apologize if English is not your native tongue.
Then I guess he won't be using his comment history on HN as a reference for his next interview.
"Managers, salespeople, and lawyers with [a] poor understanding of math as basic as adding fractions are very risky. It's not that they can't perform most job functions, it's that they are extremely likely to make costly mistakes. 'When should I add one more person to keep people from charging as much overtime?' Or, the old: 'Should I offer overtime or comp time?' etc. As [for] salespeople and lawyers, effective negotiation require[s] them to be able to say: 'I can't drop the price any more but I can do X' (which costs us less), etc.
"Graphic[...] designers often use a lot of math directly when working out layouts and things. An intuitive understanding and lots of effort can help compensate, but it's a significant loss if they can't do simple math on how tall / wide things are when you scale them."
Is that written poorly enough to take the time to passive-aggressively call someone stupid on the internet?
Maybe someone should start working on a text-to-speech app for HN with built-in meaning detection, then? Without one, onemoreact's posts unfortunately were not read out loud to me, and I had to do double-takes for "vary", "preform", and "incite" (all real words pronounced differently than what was intended). The missing punctuation also made it difficult to parse the text given the absence of verbal pauses or tone changes.
It'd be different if the argument was incoherent, or took a huge amount of effort to understand.
English is my second language, and I sorta know a couple more and could have a nice rant about English orthography and phoneticity or lack thereof and the root causes of this unfortunate situation. English as a second language issues might cause one to confuse "vary" and "very" but will not be the cause of pluralizing with an apostrophe. The lack of quotation marks is also at best a laziness issue, not a dyslexia issue.
I really struggle to see why someone would go to the effort of posting a comment and not bother to correct at least the spellcheck-catchable typo "extreamly."
Pluralizing with an apostrophe or not using quotation marks are even common with people who have English as a first language, and are signs of discomfort or lack of practice with English writing, which could be the result of dyslexia, English as an eighth language, or any other reason. Could even be stupidity, but when the ideas are coherent, to jump to that just seems to be a way to feel superior to someone.
Seemed like an intelligent enough comment to me, even though I would extend it to the reading comprehension that the author of the subject of this thread must lack to fail a 10th grade reading test with 62%, then further extend it to become a belligerent attack on management in general. The school boards in America are still debating evolution every single year. I add, of course, that school boards have nothing to do with teacher's unions, and break them more often than they support them.
I wish you luck in your struggle.
