I think they're good comments: and, I commend the desire or attempt to improve the quality of answers; and I wouldn't mind seeing more participation (from Hugh or others) like that.
Beware that sometimes comments can be done badly, for example:
- "You're wrong!"
- "Your whole school of Buddhism is wrong!"
Two of the things I like about these specific comments of Hugh's:
- They're specific (about what's wrong) and prescriptive (about how to improve it)
- They're posted to benefit the OP, to try to ensure that answers fully address the OP's question.
Apart from benefiting the OP, it's also proper to post a comment if you don't understand the answer:
- "I didn't understand this bit of your answer, could you clarify that?"
- "Could you post a reference, where I might read more about what you wrote?"
If you think that an answer should be better, it's also proper to try to a post a better answer.
The one slight criticism that I have of Hugh's comments is that they impute a motive, e.g.:
you care more about making sure that Buddhism is compatible with science instead of answering OP's doubts
I don't mind writing "you" conventionally, but I avoid writing "you" when I'm writing criticism.
