Hacking Traffic Lights

I know, I know, I have no sense of humor, and I'll lose what little karma I have, but oh how I wish I had enough karma to flag this. I came to HN because I was told it was the preeminent site for computing, technical material, and insight into startups and entrepreneurship.

I think I was mis-informed.

I also don't understand why it's being upvoted, unless it's just adolescent schoolboy humor. Is it true that on average, and with some exceptions, geeks generally have a maturity of 5 to 10 (or more) years less than their chronological age?

Is there a technical site with a more mature audience?

Urgh, the site had some pretty NSFW ad images in the margins when I loaded it. It would have been nice to have a warning.
