That seems like a terribly unfair assumption. There are
many people who can craft good useful code who can't write
worth a damn. You shouldn't penalize them for it,
especially considering how many developers speak
English as a second language.
Second, people may be withholding their code precisely
because they fear being laughed at. It's hard to be a
newbie! So if you offer a helpful answer that is bracketed by
criticism, it is tremendously discouraging. I'd like to
suggest to you that if you (or others) do choose to offer unsolicited
advice on other parts of their code, that you do so with
x-treme kindliness.
However, I must also say that I find your writeups
generally chock full of information I can use!
It is much appreciated.
