Hi Patrick,

the problem is we cannot at all control how people rate extensions. I 
see no technical way on how to restrict certain criteria to certain 
people, not to mention the administrative overhead of this. Truth is
we cannot tell

* if a user has even used the extension he rates
* what skills and understanding a reviewer has
* what intentions and criteria lead to the ratings

As my professor would say: We don't have to rely on individual 
reliability which *can* be considered as random, but as 
http://en.wikipedia.org/wiki/Law_of_large_numbers tells us, this will 
even out with the number of ratings. This is why rating averages for 
extensions will not even computed if there are < 5 ratings available.

I will discuss on how we will label the three dimensions, but I don't 
think adding more will help but only complicate the ratings.
