How can beginners in languages choose their own best answer?

Question

If you're beginning to learn a language and have a difficult question(and some really are, even for native speakers), why don't leave the choosing of a best answer to people who really know?
If you know the answer, why ask?

Answer 1

And how do you know that people chosing the best answer are entitled to vote for it ?? Too many of my answers to questions about Italian have been not voted as best in favour of translations given by weird people using on-line translators.
I understand yr point of view but believe me that what you suggest is not the solution to the existing problem. Also the thumbs up and down are not a signal since there are trolls who give thumbs without any aquaintance or reason.
On the contrary I guess who makes a guestion pertinent a different idiom has always a base, even if poor, of that language which allows him, just by reading all the answers, to distinguish a good reponse from a bad one.
Usually native speakers ( same as I'm always doing ) are correcting bad answers given by users of on-line translators or posted by totally misinformed people and this is helping the "unaware" askers to choose their own best answer.
