For ranking the results for a package search, a download statistic could be very useful and could easily be integrated. If such a statistic would be available in machine readable format (csv, xml, plain text, ...), we could integrate that.

Ordering by nr of direct/indirect reverse dependencies might also be useful. We could add a .csv file version of the main reverse dependency page which you can index easily: http://bifunctor.homelinux.net/~roel/hackage/packages/archive/revdeps-list.h... We should probably compress the .csv file to reduce some network bandwidth. Although that's not really a problem for us because we're on a high bandwidth link. Note that .csv files are already provided for individual packages. Here's the one for the latest network for example: http://bifunctor.homelinux.net/~roel/hackage/packages/archive/network/2.2.1.... Format: package name-version, nr of direct rev. deps., nr of indirect rev. deps., 'D' for Direct rev. dep. and 'I' for Indirect rev. dep.. Regards, Bas
