I posted a question.
Seconds after I received the first answer: was incomplete and did not get the expected results, clearly detailed on the question. Even more: his own posting shows the error.
The poster, also ask if his answer was OK; I was not expecting to turn the question into an interactive session.
Another answer comes after a short time, complete and working and, after testing, I accepted as answer.
The first poster got upset, posted comments complaining why I did not tell him that his answer was incomplete and a) Downvote my question and b) Magically he starting receiving upvotes!!! (btw his answer was plain vanilla)
The accepted answer, shows knowledge and experience, complex and well documented, receive less upvotes than the wrong one (and my question... still in the red).
This smell rotten fish. (ref: 475922)
btw: as a courtesy to other, I removed all my comments from the referenced question.
