(Internet shortcuts) What's on your Speed Dial?

I use the Firefox add-on, Speed Dial, which displays a set of live-preview shortcuts of your choice on each new blank tab, and/or allows respective keyboard shortcuts in the form of Ctrl+# to be used at any time.

If you have this, or some equivalent, what is on your ‘Speed Dial’?

If you don’t have it, and you’re about to get it because it’s so awesome, what’s gonna be on it?
