There's a bazillion ways to discuss a topic that don't involve giving advice with unearned confidence. Even just saying "My experience is that doing X helped" instead of "You should do X" is a massive massive difference.
Now this may be due to sampling on my end, but I did find the difference extraordinary when asking the same questions to different people.
If it's the former, I'm ambivalent. I don't give advice as a general rule. If it's the latter, I find that totally silly.
