I just answered my first question here on Data Science Stack Exchange. I am a somewhat regular user on SO and Programmers.SE. By that I mean that I have some experience using this kind of sites, and I know a bit about their policies — however, I do not know much about the particular policies of this site.
I find it quite surprising that code highlighting (a.k.a syntax highlighting) is not enabled on this site. I would expect code snippets in R, Python, Scala and (possibly) Java to be required fairly regularly to answer questions, or to ask questions at all.
Other questions that would benefit from code highlighting:
(Please note this does not mean answering to questions of type "this code is not working", which arguably could go to Stack Overflow. I can imagine asking "how do you classify this kind of data with these constraints", and the answers would be much more helpful if they included a snippet, ideally in the language and platform that the question author requests.)
