It's funny, I was commenting to a friend a couple days ago that I really liked arclanguage.com because people were hacking there instead of talking about hacking or arguing about hacking. Kinda at odds with what I'm saying on this thread. Maybe I'm just a natural contrarian.
I dunno. I could certainly be wrong - I was about Reddit. (Though I was also wrong about Xobni, and they did basically the opposite of everything PG suggests in this article.)
