According to Pingdom & Google Developers Tools, it looks like a plugin called AddThis is what's slowing you down the most.

You're using Super Cache, which is ok, but I would suggest two things:

1. Get a better social plugin. AddThis is killing you at the moment.

2. Change from Super Cache to W3 Total Cache, then activate the first two modules. Test the speed on http://tools.pingdom.com - then activate database caching. Run the speed test again. Disable database caching and activate object caching.  Run the speed test again.

Whichever configuration of the three (both database & object off, database on, object on) works best, use that one. They work differently on different hosts/configurations but your site speed should improve a lot.
