Stéphane Gimenez asked this question earlier today and it would make sense to me if the code syntax highlighting option were enabled for Bitcoin.SE. Granted we're nowhere near SO levels of code-sharing, but we do have development, programming, source and code tags and a fair amount of code-sharing does occur (mostly PHP and Python but some other stuff) for which syntax highlighting would be quite helpful.
The real question is one of scope: if a question is sufficiently about coding that syntax highlighting would be that helpful should it have been asked on SO instead or are we willing to discuss things like the Bitcoin (and related projects') source code here? If the latter, we should probably get this feature enabled. What does the community think?
