Depends who you're worried about having the EXIF data. Sure Facebook strips the EXIF before rehosting the image for others to consume, but given Facebook's nature I'm certain they use the EXIF data to track you.
If you don't want Facebook knowing exactly where you were at a given datetime, you'll still want to manually strip the EXIF before uploading.
