Suggestion: adjust 'friends rating value' by compatibility

If more than one friend has rated an item i would like to have a 'friends rating value' which takes the compatibility of that person into account.

example:
friend a, compatibility 90%, 10 stars
friend b, compatibility 50%, 2 stars

current value: 6.0
adjusted value: 7.1

Good idea I will try and integrate this somehow.

thanks
