JokesByKids Gets Social!

Whew! Just added social sharing buttons to JokesByKids that let you share individual jokes via email, Twitter and Facebook.
Below each author’s byline (the one that says who submitted the joke, and where they live) is a row of buttons for sharing on various popular services. What goes on behind the curtain (so to speak) is that you are not actually sharing the URL you are currently visiting, but rather a unique URL that features ONLY that one joke.
Without getting into a lot of tech babble, this seemed like the best way to implement this, because otherwise if you are sending a friend to a category page (for example) there might be newer, different jokes there by the time your friend came to visit.
Make sense? Thanks for your feedback. I especially want to know if you think the layout or the buttons are confusing in any way!
