On Saturday, June 23, the whole day is dedicated to cleaning up Drupal's issue queue. Our goal is to review all patches in the "patch (code needs reviewed)" state, and set their status to code needs work, duplicate, or ready to be committed. The issue queue is generally pretty slow, so those 400+ issues to review should be picked out before Saturday. It might also be helpful (and fun) to find someone to review with on IRC. If you can't agree with the patch, find someone in IRC to talk to.
We hope to make that 428 patches to be reviewed into 0.
