I love this plugin. I tried most of the plugins for cache support, but they were either to complicated or actually made my blog slower. Quick cache is easy to use and just works with basically the click of a button. It does have more advanced options for those who are technical enough to tweak and optimize, but I simply turned it on and let it be. Took about 1 second off average load time. May not seem like much, but the site was fairly speedy to begin with.
