This was in a Blog made By Baby Jesus, I think the new feature sucks cause it takes away from picture ratings !!
Basically, it works the same way as the photo rating system. you can now rate someone every 7 days, and every 7 days (or anytime after that) you'll both receive full credit for the rating (including rating count). just as before, you can *always* re-rate anyone at anytime, but if it hasn't been 7 days you won't get any points/credit for it.
previously, a member could only rate another member once... and that was it. i think this new way is more fun and gives everyone a reason to show their friends more love, more often.
YOU DONT GET POINTS IF YOU RERATE THE SAME PERSON WITHIN 7 DAYS.
