Old question, but still valid as I came across the same one. Shouldn't it be possible to make at least people from my facebook friendlist visible of liking my activities? Obviously the likes came after sharing the activity on my wall (not publicly) but I will never know, from whom :(
Along the same line, Facebook does not recognize when someone Facebook likes a workout on the Garmin Connect site. In other words, Facebook does not send notification of the like, and the like does not appear on the wall of the liker or the likee. So what is it, really?
