Let's not then? Let's translate the existing maemo.org karma interface, but only give raw numbers. Instead of assigning a certain value to each individual item, let's just throw the numbers up there for the overview. How many bugs have you filed? How many posts have you made? etc.

We still have the top lists for each category, but no overall number. Comparisons within each category are generally pretty valid but if we make no attempt to assign value to each type of contribution then much of the contention goes out the window.
