It doesn't matter. Having a hammer, gold star or whatever doesn't mean crap if you are giving bad advice to somebody.
People should generally wait for advice from a variety of sources instead of believing the first high-rated source that might actually just be as clueless as they are.
That's not to say the system is awful, fact is if you actually got 10 'best answers' then you must at least have some clue. Yes even you upendra 😀
