I find it weird that people use Stackoverflow as a community where they hang out and spend time. The obvious way to use Stackoverflow is when you're having trouble figuring something out you get there via google. While doing your research you might come accross an unanswered question that you know the answer to so you write it up. That's it. It's a very useful site but there's no need to get emotionally involved with the reputation score.

As far as using the score to get a job, I don't buy it. If you're actually good at some topic you will be able to get a job regardless. If I was hiring someone who was pushing their super-high Stackoverflow score I would be suspicious why they spent so much time gaming a dumb score on a website instead of building cool stuff.
