Sorry guys, but installing this plugin broke my WordPress Visual Editor.
It also prevented some of the clever core functionality from working - for example, the way a link to a tweet on its own line is turned into an embedded tweet.
It is definitely the fault of the plugin not playing nicely with the core functionality. I am using WordPress version 3.4.1 and 1.0 of the plug-in. I am using Firefox, version 14.0.1. I also have the JetPack plugin installed.
Sorry to be negative but I hope this is useful feedback.
