In reply to Justin Tadlock.

I often wondered if the directory should be set up to de-list or completely remove themes that are a certain age and that have not been updated. The trick would be to determine the criteria by which this would be implemented.

However, as I just posted in a comment above to Max Ziebell, I would love to see a completely new theme directory built and then phase out the old--much easier to do it from scratch than fighting with the old one. Although, developing a new directory from scratch is a huge undertaking.
