Arie Nagel (or ainigma32 on Drupal.org) is a relatively "new" face in the Drupal community (he has yet to reach his one-year anniversary on Drupal.org), but yet has already made a profound impact on our project for the better.
How? By answering the cries of fellow Drupalistas' requests for help!
Arie has done a laudable job farming the Drupal core issue queue for support requests, closing out old ones, asking for more info on unclear ones, and helping out on those that he can. His tracker page shows a nearly endless stream of helpful, courteous responses, and he shows genuine concern for making sure users find the answers they're looking for. This is a tremendous contribution to the Drupal project. Hats off to you, Arie! :D
Without spoiling the interview ahead of time, something that Arie alludes to that I can back up whole-heartedly is that helping other users with support requests is the single fastest way to skyrocket your way up the Drupal learning curve. If you don't know the answer to something, seeking out the answer for others will give you a chance to teach yourself in a very practical way (or learn from others who end up answering the person's question). And if you do know the answer, nothing cements a topic in your head more than explaining to others how to do it. Finally, even if you consider yourself a total "newbie", believe me, you still know more than someone else out there, and you are far better positioned to explain it to them in a way that makes sense.

Here's Arie's interview where he discusses how he came to Drupal, what motivates him to help out, and some ideas for improving Drupal support in the future.
