Stay up to date with Drupal, and discover good Drupal resources

Planet Drupal aggregates drupal related blog posts from a number of drupal sites and bloggers. I've only recently discovered it, but have already found some incredibly useful drupal posts here. For example, this one shows you how to allow "everyone, including “anonymous users”, to be informed of updates to nodes right inside their content", something very similar to what a client has just asked me to do.
