I noticed Larry M. used a short URL for the ESV in a Facebook post, which redirects to their main Bible study site (unfortunately, in my mind): http://esv.to/
The NLT also has one: http://nlt.to/ with the Bible text only, which I like.
Do you know of any others?
These are good for emails, Twitter, and other spots where space is at a premium.
UPDATE: I forgot a good one: http://ref.ly/ but I’m not sure what versions are available with it.
