@Alina Because, we don't believe we've got the answer. And again, Alina, I am on the other end of the spectrum from pnuts. He's the one with a problem not ME!! I am doubled over with my audacity. But it is true! I get in trouble all of the time making an answer that should have been a comment. Have you not seen this? I am bad. Pnuts, has had incredible information that should have been made into an answer. That has bothered me!
Well, sometimes you have a tendency to divagate, but now I was referring to this post on meta where you posted a useful answer (in my opinion) in the form of a few comments. I have also noted that pnuts posts comments lately instead of writing answers and I was thinking maybe there is a reason for that.
@pnuts You have some good answers and some other answers that are not so focused. Writing questions, answers, letters, improves our style on the long run. Some of the info you provide is very interesting, so please post them as answers.
