It's not the tiny icon at the top I'm referring to. It's a big floating Facebook image (button or whatever) that appears in the lower right of the viewing pane and is unaffected by scrolling. If you're not seeing it, you may be running a different browser (I use Firefox with the Adblock Plus extension).

Blocking Facebook isn't a feasible option to avoid garbage like this, because there are times when one wants to view someone's Facebook page for some reason (without having to become a Facebookie).

And Max, if people like me don't express our displeasure early, developers assume everyone likes the things you keep cluttering the screen with. I stopped watching TV partly because of the distracting garbage they clutter up the screen with, distracting from the program I'm actually tuning in to watch. If this is "value-added viewing", why don't they overlay it on the commercials instead??
