@wkempf: You aren't missing anything. FB is a gnat that bothers me and I prefer Bing. Yes, this is about Bing, then. IE9 cannot shake the FB encroachment without a bunch of registry hacking and 3rd party tool, so no thanks.
It is a purely personal peeve. I want to absolutely ignore FB and push it into the recycle bin everywhere I find it. I doubt they are paying Bing for space, but I just want to erase the [Like] buttons and sidebar branding... please go away FB.
@MasterPie: I have no apps or services connected to my account... thanks for the info, though.
