Wrong URL is being called in TopBar

In this article: http://www.danielodio.com/2012/04/12/...

there are a few problems with the TopBar:

1) The wrong URL is being called. You can see that the TopBar is referencing the post "Efficiency Hack: Hybrid hard drive" in this screenshot: http://drod.io/411A2Y1e1H2Z2m3I1U2j. That's an old article, not the current one for that page.

2) The Facebook button isn't showing.

Here's what my implementation looks like: http://drod.io/053k3O250F1a3z2M2H1P
