Thanks for this good work. This is going to be really useful!

Indeed. One of the main duties of TU is to maintain popular packages in 
community. But in most cases (myself included!) the packages being 
actually maintained reflect more the TU's own needs and interests than 
those of the community. This is something we should discuss. Also it 
will be interesting to compare the figures from pkgstats with the number 
of votes in AUR. I guess they should be relatively proportional, but 
there may be important exceptions.

Huh? I thought these are only of interest for x86_64 users, no?

We need to analyse this carefully. Obviously extra and (especially) 
community do require some substantial cleanup...

There are some strange stats. For instance pacman is "only" installed on 
99.92% of the systems that were submitted!! How can one have an arch 
installation without pacman? And how can one use pkgstats without it?!
