oh, that's a shame. Drupal's packaging system requires everything on branches, not HEAD. So that's a lot of contributors without any credit on here. Happily though, they're moving to git.. (i predict it'll take at least another year to get there)
The latest commits ohloh noticed are 3 months old: https://www.ohloh.net/p/debian/commits It's fetching the git repos, but not processing them. I can't find my recent debian packaging commits in ohloh.
the development time isn't a problem -- just point out where we can get the source code.
Many projects use media wiki, tracks or other tools that let you work out, line by line, version by version, who wrote what. How about reading these to give documentors, the other heroes of opensource, the credit they deserve.
