I heard that many people had issues with W3 Total Cache on a WordPress MultiSite install. And then I see this on the plugin page:
Compatible up to: 3.2.1

Seeing that I'm running on WordPress MultiSite Version 3.4.1 and that it's been over a year since the last plugin update, I'm really wondering if this plugin is a good choice for me.
