Really? His typo invalidates his premise about how to teach engineering in a fun and engaging way?

As far as I could tell, his main concern was for the curiosity and motivation of the students, not their ability to communicate via the written word.

Typos may detract from his post, and nitpicking is fine, but your first sentence is illogical, incorrect (it's not a spelling error), and unnecessarily negative. Take it easy with the attitude, man.

Of course the typo is logically irrelevant, and yes, I should have referred to diction rather than spelling.

But I don't think my point is illogical at all. Statements like "College is broken" (the original submission title) are counterintuitive (outside of HN, anyway) enough that they strain credibility. Sloppiness strains it further.

You're right on the unnecessary negativity. It would have been more helpful to note specific typos in a friendly manner. What was posted, however, was just my knee-jerk reaction upon opening the link. That said, though it doesn't serve as a good excuse, I doubt I'm the only one who might react as such.
