Until yesterday you could not share a Vine video URL if you forgot to share it when you posted the video.
I posted this answer on Quora today:
Starting with Vine v.1.05 (released Feb.05, 2013) you can share your Vine video on Twitter and Facebook. Go to Your Profile, scroll to the video you want to share, then click on the 3 dots (…) under the video to the right. There you have the option to share on Twitter and Facebook.
See the images below.
Enjoy my latest video, see how my salad disappears!
