The question https://tex.stackexchange.com/questions/50373/what-dont-do-latex-text-composition shows that it is closed by me (and others) as “not constructive”. I did however vote to close it as a duplicate of Best practices references. So the question now gives a wrong representation of my vote (I am of the opinion, that the actual question (“Is there a list of LaTeX best practices?”) is interesting, and we shouldn't close as “not constructive” because of bad English).
Thanks for bringing this up. I cannot reproduce the close reasons issue with the current build of our network sites. Please let me know if the problem remains for you.
