I'd like to see hackage maintain download stats and have cabal-install
report build success and failures (with build logs) along with basic
config info like versions of deps, platform, compiler etc.

This could make a great distributed testing system.

Yes, I would like to see activity info for each package. What I'd really
like to see is each package linking to it's darcs repo and generating an
activity graph using dons's darcs-graph program. Though I'd also like to
annotate the graph with marks for each release.
