Interesting. Perhaps they should be performing traffic analysis to see who's busy, and who's not?

I love to debate (reddit has saved my wife a regular earful), but I can't imagine surfing when I'm really "in the zone". I tend to do more directed documentation queries and explicitly avoid sites like reddit where I'm likely to become mired.

So yeah, for me posting frequency is inversely correlated with how busy I am. On the other hand, all of that reading, researching and debating generates a lot of new ideas.
