So... Congratulations on graduating to a full-fledged Stack Exchange site!
We'd kinda like to do something special for y'all, and this is currently the top-ranked feature request: Add Markdown and/or OneBox support for BibleGateway
That said, oneboxing is troublesome. BibleGateway doesn't offer an API for this, so we'd be stuck trying to scrape the site's text, which is fragile... And then there are potential legal issues that we probably don't want to worry about.
However, Pacerier and Iszi laid out a reasonable idea in the comments there... What about a special syntax for Markdown here that enabled quick generation of links to specific passages and translations?
[bg Matthew 1:18]in Markdown would convert to Matthew 1:18 in the output.
[bg Genesis 1:1-5 NIV]in Markdown would convert to Genesis 1:1-5 (NIV) in the output.
[bg Ecclesiastes 1:18 NIV;KJV;NKJV]would convert to Ecclesiastes 1:18 (NIV;KJV;NKJV)
The only question is, would this actually be useful? If you're quoting a passage anyway, then you probably already have a link ready at hand. Is this a feature that would actually improve the experience here on the site, or would it just end up being extra baggage?
