Okay, so I had my Facebook page open (as usual). While procrastinating studying for a final I checked GLP and went to a Norwegian site about the spiral today. This was in a different tab. After I watched a video on one of the Norwegian sites I closed it and went back to my Facebook tab was was greeted by "Would you like to use Facebook in Norsk (bokmål)?
Facebook is available in 70 languages. Click here to switch to Norsk (bokmål)."

Sound like spying to anyone else? I've never once been asked if I wanted to use Facebook in another language and find it highly coincidental that it would ask if I wanted to view it in NORSK immediately after I visited a Norsk site.

Thoughts?
