If you are a native English speaker, higher education should not be required for basic writing. There is no requirement to use complicated words, but I'd expect someone to be able to spell correctly (especially on a device with spell checking).

If you are not a native speaker, corrections are one way to learn from your mistakes and improve your English.

If you are in a hurry then maybe you should wait until you are not in a hurry before posting to HN.

I do agree that correcting someone often comes across in a bad way, but at the same time so does leaving a comment riddled with mistakes.
