If posting a screenshot is easier for the user than posting the code, then maybe the system should gently bend itself towards that?
Posting code on SO is actually quite hard and I’ve struggled with it myself. When you paste a bunch of code, it starts off as being formatted as text, and you must do lots of work to restore the indentation and the like.
Maybe this is a source of pride for some people who can do that, but in some cases I’ve honestly found myself thinking that instead of messing around in the Markdown editor, I’d like to drop a screenshot in from where the code gets OCRed out with already the correct formatting.
Maybe it’s required qualification for using the site that you can correctly format and post code. Or is it another of those things that discourages new people? I don’t know, I haven’t studied usage as much. But certainly the code-posting experience itself could also use improvement. Maybe also something like, if you paste in something that looks like code, then apply correct formatting to it, don’t require me to do gruntwork to fix it.
