>>221
This is a typical writing which I consider
"this mostly makes sense but is clearly written by non-natives".
I can't really explain what makes it sounds unnatural but it truly is.
My hunch is that the writing contains a lot of phrases which I don't see often
when I read English written by natives (or very fluent non-natives).

I recently have been spending way too much time here, much more than I should.
From what I have seen in the past week,
I know that there are at least two guys who have decent understanding
of english and the two posts you pointed are the ones written by these two guys.

So stop trying them.
The fact that they wrote long in Japanese (in particular the >>220 guy tends to
write a lot in Japanese) does not mean that they are not good at writing in English.
