How important is the orthographic/typographic rigor? Science and Orthographic/Typographical Errors



Some people appreciate the attention to have their orthographic/typographical errors corrected/pointed out.

Others find it uncool to just point formal errors, finding it ideal to jointly comment on the content.

Given that, in terms of scientific rigor, how important is the orthographic/typographic rigor? And how does that vary?

As a side note, on a personal level, I find that reading a scientific text with orthographic/typographical errors is quite a turn off.
Orthography and typographical correctness are much less important than scientific (methodological and theoretical) rigour. Yet all scientific publications should of course also be well-written, and in general there's nothing wrong with casually pointing out a typo, wrong glyph, or similar glitch.

However, if you're writing a review, grade a student paper or discuss a presentation, this better not be your only comment!
