Oh, I misinterpreted what you meant then. Regardless, your logic is sound and has lead me to think about things I hadn't considered. So, from now on I won't disregard grammar errors but will instead use them as evidence. That said, I'm kind of stuck on how to proceed when the ideas in a comment are trending towards valuable but I reach a grammar error. Maybe how to handle those is just a function of personal preference or available time? Also, based on your experience, should I consider user names as part of the available evidence?

They're weak evidence. If the first half of a comment is valuable it's probably worth reading the rest. And yes, username is strong evidence. I read every comment I see from patio11, for example.
