Anonymous has a perception problem. Most people think we're a group of shadowy hackers. This is a fundamental flaw. Anonymous is groups of shadowy hackers, and herein lies the problem. Anonymous has done a lot of good in just the past 9 months. It has helped with other groups in providing aid to people on the ground in countries where "democracy" is a bad word.
The mainstream media needs to understand that Anonymous isn't unanimous. I've yet to see wide scale reporting make this distinction. A destructive minority is getting a majority of the press, while those of us who toil in the shadow doing good work for people at home and abroad go unthanked.
Finally, hacking isn't just about breaking into web servers and leaking data to the public. Far from it. Hacking is just as much about breaking out of things as it is about breaking into things. Hacking is lifestyle, and a mindset. It is about learning more about the technologies we use and social norms we are subject to.
Don't let the actions of a few skew your perception of hackers as a whole.
