I'm currently working on an answer that will include a bunch of code for a working example. I figured it'd be a great opportunity to try out the new snippets feature but it appears that we don't have it. See here for info about Stack Snippets.
Considering the lack of coding in questions and answers, do we really need this feature?
Are there any reasons for why we wouldn't want this feature?
Are we allowed to have this feature?
When and how can we get it implemented if we do want it?
I personally think that over time, this feature would probably add a lot of value to our site. It would allow us to render SVGs on the page, show working examples of code and overall, we'd probably link to less external sources to support our answers (sending users away from our site less).
I can't think of a good reason why we wouldn't want it, except that maybe it'd be a pain to implement - but I doubt that very much.
What does our wonderful community think?
