hefay: at one time I would have agreed with you. Actually I still do agree with your assertion that if you are only here for the points it will be en exercise in futility.
For many months I really did not pay attention to how many points I was accumulating. I also never used Rocket Record, even though I always echoed every sentence in every lesson.
But at some point I realized that without my knowing it, my point total was getting up there, and if I made sure that I got points for what I was doing, I could get into the top 10 Spanish learners. Once I got there, I set my sights on moving up the ladder. Now I am solidly in 5th place, and looking over my shoulder because David M38 is creeping up on me.
So I have to say that for me, the points have been an additional motivation. It is sort of like getting a gold star or an A in school. I didn't get many of them back then so I am making up for lost time now!
