Can't really say for anyone else, but please do correct any of my answers anyone for typos and minor errors right away - it's greatly appreciated :).
Some people notice typos much more easily than others. I'm not one of those. I can read and re-read an article with many typos and even silly mistakes in them and not notice anything. I'm often corrected and am grateful to those who do the corrections.
Only thing could say about "netiquette" - this is a very minor thing - if you have other non grammatical / typo type changes - like rewording a sentence in a way that somewhat changes the meaning of the sentence or changes the conclusion etc - it is helpful to keep that separate from typos and minor errors.
I.e. to submit the typos, then as a separate edit, or as comments, the more substantial change. And if you have any corrections that would do with some discussion, then best as comments first.
That's because Quora only shows the first few changes so you could end up saying okay to what you think is a minor edit when it isn't because the first few edits are minor.
Also, so that you can easily approve the minor edits fixing typos etc all in one go, without needing to re-edit the article back to its original meaning if you don't agree with the more substantial change.
That's because it's an "all or nothing" thing either you approve all the edits or you don't approve any. Only happened to me about once, I ended up not approving the edit (which had a small factual error in it or some such, can't remember the details now) and doing the suggested minor typos by hand.
The more edits to fix my answers the better :). On wikipedia people who do this sort of thing are known as WikiGnomes
