 offering them a way of scaling it either -1 or 1.Aren't stars redundant
with faves & buries? It seems to me like giving someone a way to rank an
application on a scale of 1 to 5 is better than  I thought the whole
point of application karma was to mix ideas of quality, popularity and
viability to come up with an overall ranking of applications. Was I wrong?

They're stored somewhere - there's a curve of downloads on a
month-by-month basis in maemo.org/downloads when you click on the
"Download statistics" link on (say)

I'm suggesting using the last full month's worth of downloads as the
"recent downloads" measure. It could just as easily be the last 3 months
or the last 6 months. The point is to get an idea of how popular the app
has been recently, as opposed to 2 years ago when it was the hot new
thing on Bora.

As for the coefficients, I agree, they need tweaking to be both simple
to implement (for you) and in a reasonable range for the applications.
We don't want one app at 10,000 karma while 99% of the apps are under
10. The karma distribution should be like the person karma one.
