In the sense that... it's noise.
We don't like noise. Your question isn't just helping you, it's helping others, and 5-10 or even 15 years down the road, your politeness will be irrelevant. The person seeking it will get answers.
It's enough of an issue that we have a standard moderation message for this (as well as signatures), and part of it explains both the confusion you have, and why we do things the way we do...
Coming from your traditional discussion forums, I understand that it is often customary to be a bit more cordial and chatty in your posts, but at Stack Exchange, one of our goals is to build a library of high-quality questions and answers where it's as easy as possible to find the best answer. I know this can come across as a bit persnickety — this crazy Q&A site that hates conversation — but it's that "just the answers" ethos that results in over 90% of the questions getting great answers, often stunningly quickly.
If you want to make someone's day, upvote the post, pick the best answer and close the loop. Be responsive and edit in additional information as needed (which is the best thing!). If you end up self resolving, post an answer. In a sense, "focus on the content not the people" is one of the hardest things to get about using SE effectively.
It's okay to keep it technical, and to the point, simply because that's how we do things.
