In what way is this an actual problem?

Why would we need to do something about that? In the case of [your answer][1], which now stands at +8, with the next follow-up post at +1, I don't see why an "accepted" checkmark would change anything here.

For a random visitor—remember that 90% of our traffic comes from search engines—all that counts is that the most useful stuff is right at the top. If you're a person in search of help, would you really care if the question is "officially" marked as answered in our system or not?

With such a large gap in votes, it should be evident that your answer seems to be the solution.

Now *this* is a bit different. To a random visitor, all of them seem more or less right. But: Can't you try if the answers are indeed correct or not? You have an account, so **make use of your votes or comment ability** to make the Q&A better for any visitor. It is your duty to vote for what is useful and what is not.

The whole point of Stack Exchange is that good and useful answers sooner or later float to the top. This happens somewhat naturally, although of course it takes people to *read*, *try* and *vote* for answers. As an active member, **this is your job.**

If enough votes and feedback have been collected, the best answer will be quite obvious. There's no real need to accept it to further distinguish it from others. If you're just looking for help, you'll probably try anything.
