We've had more questions lately in which people asked about specific code from various Bitcoin-related codebases. I've also been approached by a developer who requested that we get Code Syntax Highlighting. I reached out to the Community Manager team who told me that it could be made to happen if the site's community agreed.
Please weigh in: Do we want Code Syntax Highlighting for Bitcoin Stack Exchange?
