I'm thinking that possibly the Abandoned category should be relegated to a checkbox or something. Normally I don't want to see any Contribs that aren't actively being developed. So some other way of filtering it, either a checkbox ("Show abandoned Contribs?") or making combination filters, a la the way Drupal.org's Issue Tracker works, would be great.

Some suggestions:

Work in Progress
Ready for testing
Complete and working
Abandoned
Broken
Deprecated
Bug Testing
Active (WIP, Testing, Complete)
Inactive (Abandoned, Broken, Deprecated)
